Biology-Cells

PLANT AND ANIMAL CELLS  HAVE SIMULARITIES AND DIFFERANCES:

Animal Cells

• Nucleus- contains genetic matireal + controls activities of cell.
• Cytoplasm- gel like substance, where most of the chemical reactions happen. Contains enzymes that control these chemical reactions
• Cell Membrane- hols the cell together and controls what goes in and out.
• Mitochondria- where most of reactions for reperation take place. Resperation releases energy that the cells need to work.
• Ribosomes- these are where proteins are made in the cell.

PLANTS CELLS BASCILLY HAVE THE SAME FEATURES AS ANIMAL CELLS BUT HAVE A FEW EXTRAS THAT ANIMALS CELLS DONT:

Plant Cells:

• Rigid Cell Wall- made of cellulose. It supports the cell and strenghens it.
• Permanent Vacuole- contains cell sap.
• Chloroplast- these are where photosynthesis occurs, which makes food for the plant. They contain a green substance called chlorophyll. 

YEAST IN A SINGLE-CELLED ORGANSIM

Yeast is a microorgansim. A yeast cell has a nucleus, cytoplasm and a cell membrane surrounded by a cell wall. 

BACTERIAL CELLS HAVE NO NUCLEUS

Bacteria are also single-celled microorganisms.

• A bacterial cell has cytoplasm and a cell membrane surrounded by a cell wall.
• The genetic material floats in the cytoplam because bacterial cells don't have a nucleus.
