WHAT ARE THE FUNCTIONS OF THESE ANIMAL CELLULAR
COMPONENTS(EUKARYOTIC)? - Correct Answer ✅Nucleus-
Contains genetic material that controls the activities of the
cell.
Mitochondria-These are the where most of the aerobic
respiration takes place, transferring the energy which the cell
needs in order to work
Cytoplasm-This is where most of the chemical reactions
happen, it contains enzymes which control these chemical
reactions
Cell membrane-This holds the cell, and controls what goes in
and out.

Ribosomes-Theses are where proteins are made.
WHAT ARE THE FUNCTIONS OF THESE PLANT CELLULAR
COMPONENTS(EUKARYOTIC)? - Correct Answer ✅Cell wall-
Is made of cellulose and strengthens the whole cell.
Chloroplasts-This is where photosynthesis occurs, making
food for the cell.The chloroplasts contain green pigments
called chlorophyll, which absorbs the light needed for
photosynthesis.
Permanent vacuole_This contains cell sap, a weak solution of
sugar and sals.
WHAT IS THE STRUCTURE AND FUNCTION OF PROKARYOTIC
CELLS? - Correct Answer ✅Nucleus-They don't have a true
nucleus, instead they have a single circular strand of DNA,
floating freely in cytoplasm.

Plasmids-Small rings of DNA which transfer genetic
information from one ell to another.
No chloroplasts or mitochondria.
Cell wall- made from peptidogylcan.
Has a cytoplasm and cell membrane
WHAT IS THE PROCESS OF DIFFUSION? - Correct Answer
✅Diffusion is the movement of particles from an area of
higher concentration to an area of lower concentration
Examples are-diffusion of gases in alveolar, fish, villi and
leaves
WHAT IS THE PROCESS OF OSMOSIS? - Correct Answer
✅Osmosis is the movement of water molecules across a
partially permeable membrane from a region of high water
potential to a region of low water potential.

Examples are- potato cells, and root hair cells.
WHAT IS THE PROCESS OF ACTIVE TRANSPORT? - Correct
Answer ✅Active transport is movement of water and
mineral ions from a low concentration gradient, to a high
concentration gradient, a process which requires energy
Examples are- root hairs and in the gut.
WHAT IS THE CELL CYCLE(MITOSIS)? - Correct Answer
✅Mitosis is used in multi-cellular organisms, the cell cycle
consists of two stages:
Interphase-This is the growth of sub-cellular components and
replication of DNA.What happens is that the cell grows and
increases the amount of sub-cellular structures such as
mitochondria and ribosomes, it then duplicates its DNA.
