- Cells and their contents
- Animal cell
- Nucleus
- contains genetic material
that controls the activities of
the cell
- Cytoplasm
- gel-like substance where most
of the chemical reactions
happen. it contains enzymes that
control chemical reactions
- Cell Membrane
- holds the cell together and conmtrols
what goes in and out
- Mitochondria
- most of respiration reactions
take place here. Respiration
releases energy that the cells
need to work.
- Ribosomes
- where proteins
are made in the
cell
- Plant cell
- has usually everything
an animal cell has but
there are a few extra
bits
- Rigid Cell Wall
- made of cellulose. it supports the cell and strengthens it
- Permanent vacoule
- contains cell sap, a weak solution of sugar and salts
- Chloroplasts
- where photosynthesis
occurs, which makes food
for the plant. they contain
a green substance called
Chlorophyll
- Yeast
- Single-Celled organism
- microorganism.
- It contains...
- Cell Membrane
- Cytoplasm
- nucleus containing genetic material
- Cell Wall
- Bacteria Cell
- Single-Celled organism
- Naked DNA
- No nucleus
- Because of
this genetic
material
floats in the
cytoplasm
- They contain...
- Cell Membrane
- Cytoplasm
- Genetic material
- Cell wall
