Cell Structure and Function. Cell Membrane Regulates what enters and leaves the cell.

Cell Structure and Function

Cell Membrane

Regulates what enters and leaves the cell.

Cell Wall

Supports and protects the cell

ChloroplastsCaptures sunlight and converts

it into chemical energy during photosynthesis; contains chlorophyll.

Cytoplasm

Jelly-like material inside the cell membrane that holds the organelles.

Cytoskeleton

Helps cell maintain its shape and is involved in cell movement.

Endoplasmic ReticulumMembrane system where

proteins are transported.Can be Rough ER (protein

synthesis) or Smooth ER (lipid synthesis).

Golgi Body/Apparatus

Modifies, sorts, and packages proteins from the ER

Lysosome

Filled with enzymes used to break down food, waste, and cell organelles that no longer function.

Mitochondria

Produces energy for the cell

Nucleolus

Makes ribosomes (located inside the nucleus)

Nucleus

Contains DNA and controls the cells activities

Ribosome

Makes proteins

Vacuole

Stores water, food, and waste
