stem cells and specialised, transportation, cell function and structure,

Cell Membrane

Controls what enters and exits the cell; provides protection and communication

Cytoplasm

Jelly-like fluid that holds organelles and supports chemical reactions

Nucleus

Contains DNA; controls cell activities and gene expression

Large Central Vacuole (plant)

Stores water, nutrients, and waste; maintains cell pressure

Mitochondria

Produces ATP (energy) via cellular respiration

Chloroplasts (plants only)

Conducts photosynthesis using sunlight

Endoplasmic Reticulum (ER)

Synthesizes proteins (rough ER) and lipids (smooth ER)

Golgi Apparatus

Modifies, packages, and ships proteins and lipids

Lysosomes

Break down waste and cellular debris

Vesicles

Transport materials within the cell; aid in secretion and storage

Ribosomes

Synthesizes proteins

Centrioles

Organize cell division (in animal cells)

Cells

Cells produce energy, build proteins, and transport materials to keep organisms alive. They also grow, divide, and communicate to maintain body functions.

what are cells membranes composed of

phospholipids (hydrophilic, hydrophobic), proteins, cholesterol, carbohydrates

• Membrane-Bound Organelle

• Found only in eukaryotic cells.

• Non-Membrane-Bound Organelles

• prokaryotic and eukaryotic cells

what are the 3 main part of the cell (structure)

what protein helkps with osmosis

aquaporine- making it a facilited diffusion

What are the 3 types of cells that will not cell divide?

• Nerve cells

• Cardiac cells

• Red blood cells

vesile

Transport materials within the cell
