The shape and size of cells are related to the specific function they perform, with some cells like Amoeba having changing shapes and others like nerve cells having fixed shapes.

Transport of materials, especially proteins, and serving as a cytoplasmic framework.

A solution with the same water concentration as the cell, resulting in no net movement of water.

Genes.

Mitosis and meiosis.

They gain water and swell.

Eukaryotes.

Storage.

Prokaryotic cells lack membrane-bound organelles, while eukaryotic cells have them.

Mitosis; meiosis is involved in the formation of gametes.

The cell.

They are important for photosynthesis.

Safranin solution.

The plasma membrane separates the cell's contents from the external environment and is selectively permeable, allowing certain materials to enter or exit.

Complex sugars from simple sugars.

The process of building the cell membrane using proteins and lipids.

He discovered cells by observing a cork slice with a primitive microscope.

The shape of the cells can be noted and drawn.

Similar small structures that form a larger structure like an onion bulb.

In A, there is no solute to create a gradient, and in D, the boiled potato's cell structure is damaged, preventing osmosis.

He saw many little compartments, which he called cells.

Not well defined and not surrounded by a nuclear membrane.

Nuclear membrane.

To prepare a temporary mount of onion peel for microscopic observation.

Plasma membrane, nucleus, and cytoplasm.

Cell division.

The egg shrinks as water passes out into the salt solution.

It stores, modifies, and packages substances manufactured in the cell.

Organic molecules called lipids and proteins.

The term 'protoplasm' for the fluid substance of the cell.

The cell would lose its integrity and could die due to loss of essential substances.

Generally small (1-10 μm).

Transfer of material between the nucleus and cytoplasm.

Rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER).

It allows them to exist in hypotonic media without bursting.

Entangled mass of thread-like structures in a non-dividing cell.

Most cells divide for growth.

Chromoplasts and leucoplasts.

Cytoplasm.

Four new cells.

Single chromosome.

Lipids and proteins.

Using powerful digestive enzymes capable of breaking down all organic material.

Mainly composed of cellulose.

A double-layered membrane.

To generate ATP, the energy currency of the cell.

Membrane-bound sacs filled with digestive enzymes that act as the cell's waste disposal system.

It regulates the movement of substances like CO2 and water in and out of the cell.

A cell wall composed mainly of cellulose.

It packages and dispatches materials synthesized near the ER to various targets inside and outside the cell.

Fat molecules or lipids.

They allow cells to withstand very dilute external media without bursting.

Membranes.

Cells.

Nucleus.

It was the first time someone observed that living things consist of separate units.

Cell organelles are specific components within a cell that perform special functions, such as making new material and clearing waste.

They provide turgidity and rigidity.

The egg swells because water passes into it by osmosis.

It serves as a passageway for intracellular transport and as a manufacturing surface.

Prokaryotes.

Different regions of cells get colored differently based on their chemical composition.

It helps maintain turgidity and stores important substances including wastes.

It would struggle with processing and packaging proteins and lipids.

A little room.

Different parts of the human body perform different functions, such as the heart pumping blood and the stomach digesting food.

Solid or liquid contents, including cell sap.

Air bubbles.

Organisms made up of a single cell, such as Chlamydomonas, Paramecium, and bacteria.

Nucleoid.

It helps in the absorption of water.

Chloroplasts contain chlorophyll and perform photosynthesis.

Virchow, by suggesting that all cells arise from pre-existing cells.

Through a process called phagocytosis.

The 'black reaction' for staining individual nerve and cell structures.

Presence of membrane-bound organelles.

It regulates the movement of materials between the cell's interior and the outer environment.

DNA (Deoxyribo Nucleic Acid) molecules.

It undergoes shrinkage or contraction away from the cell wall, known as plasmolysis.

Plasmolysis occurs, indicating that only living cells can absorb water by osmosis.

Osmosis is the movement of water molecules through a selectively permeable membrane.

It divides to form two identical daughter cells with the same number of chromosomes as the mother cell.

Meiosis.

The theory that all plants and animals are composed of cells and that the cell is the basic unit of life.

Mitochondria, because they produce energy (ATP).

Chromoplasts and leucoplasts.

The cell gains water by osmosis and may swell up.

A system of membrane-bound vesicles arranged in stacks called cisterns, involved in storage, modification, and packaging of products.

Sites of protein manufacture.

Draw the structures they see on an observation sheet.

They originate from a single cell that divides to produce more cells.

The process by which a cell engulfs food and other materials from its external environment.

Because meiosis involves two consecutive divisions, reducing the chromosome number by half.

Yes, as seen in organisms like Amoeba.

They have their own DNA and ribosomes.

The net diffusion of water across a selectively permeable membrane toward a higher solute concentration.

Rod-shaped structures.

Because it has ribosomes attached to its surface.

A compound microscope.

Organisms that consist of many cells grouped together, such as fungi, plants, and animals.

Scrape the inside surface of the cheek, transfer the material to a slide, and stain it with methylene blue.

They have no membrane-bound organelles, chromosomes composed of nucleic acid, and very small ribosomes.

In the endoplasmic reticulum.

Carbon dioxide moves out of the cell by diffusion when its concentration is higher inside the cell than outside.

He discovered the nucleus in the cell.

For growth, replacing dead cells, and forming gametes for reproduction.

The movement of water across a selectively permeable membrane from an area of low solute concentration to high solute concentration.

Plant cells have a cell wall, chloroplasts, and a large central vacuole, while animal cells do not.

It serves as a control to compare the effects of osmosis in the other cups.
