Features of cells and their functions

Nucleus

Organelle that contains DNA. Controls cell activities

Mitochondria

Organelles in which aerobic respiration occurs. It can't be easily seen through a light microscope

Ribosome

Site of the second stage of protein synthesis

Cell wall

Made of tough cellulose to support the cell and allow it to keep its shape

Cell membrane

Separate the contents of the cell and its surroundings. Controls the movement of substances such as oxygen, glucose and carbon dioxide into and out of the cell

Permanent vacuole

Space in the cytoplasm filled with cell sap (mainly water and ions). Its membrane is bound, helping to support the plant by keeping the cell rigid

Chloroplasts

Organelle that contains chlorophyll, a green pigment that absorbs light energy for photosynthesis

Cytoplasm

Many chemical reactions needed to carry out life process take place here. Contains organelles
