BIOLOGY CELL STRUCTURE

Animal cell

Animal cells are the fundamental building blocks of all multicellular animals, including humans. Eukaryotic cells.

plant cell

the basic building block of all living plants. eukaryotic

nucleus

. Contains genetic material, including DNA, which controls the cell’s activities. looks like a lump in middle of cell.

ribosomes

Tiny structures where protein synthesis occurs.

cytoplasm

A jelly-like material that contains dissolved nutrients and salts and structures called organelles. It is where many of the chemical reactions happen.

cell membrane

Its structure is permeable to some substances but not to others. It therefore controls the movement of substances in and out of the cell.

vacuole

only in plant cells. Filled with cell sap to help keep the cell turgid.

chloroplast

Organelles that contains the green pigment, chlorophyll, which absorbs light energy for photosynthesis. Contains the enzymes needed for photosynthesis. only in plant cells

mitochondria

Organelles that contain the enzymes for respiration, and where most energy is released in respiration.

Eukaryotic cells

Cells of animals, plants and fungi are called eukaryotic cells.-A type of cell that has a nucleus.

prokaryotic cells

Cells of bacteria are called prokaryotic cells-A simple cell that does not have a nucleus – the DNA is free in the cytoplasm.
