CELL STRUCTURE

plasma membrane also known as a cell membrane

a jellylike semi fluid called cytosol (cytoplasm) in which cell organelles are suspended

nucleus mitochondria ribosomes Golgi apparatus vacuole they serve diff functions

they are specialised structures found inside living cells that perform specific functions for the cell

it encloses the cell. and it forms the outer boundary of the cell surrounds the contents of the cell

extracellular structure of plant which distinguishes the from animal cells it s a wall that surround the cell on the outside

the cell will protects and support the cell animals do not need a cell wall because organisms are protected and supported ut their skeleton

it is a jelly like substance that fills the cell it consist of water with other components which either dissolve or suspend in it

it is a round organelle that is surrounded by a nuclear membrane and it contains the DNA of the cell

it is the organelle in the cell where cellular respiration takes place

the process in which glucose breaks down in the presence of oxygen in the cells of organisms , to produce carbon dioxide , water and energy

found in plant cells site for photosynthesis contains the green pigment called chlorophyll absorbs the light energy from the sun and converts it into energy rich sugars called glucose sugars produced store as starch

process in which plants use chlrorphyll to convert radiant energy into sugars when carbon dioxide reacts with water also producing oxygen in the process

fluid filled sacs that are surrounded by the membrane

animals - one or two small vacuoles or no vacuoles at all plants - have one or two large vacuoles which store substances like sugars ,salt ,water

• plants cells have cell walls and animals cells don’t • plants have a regular shape due to rigid cell wall – animals cells have an irregular shape • plants cells have a large vacuole – animals cells have a small vacuole or non at all • plants cells have chloroplast which enables them to make her own food –animals cells don’t have chloroplast and therefore are unable to make their own food

dddd

to control the movement of materials into and out of the cell it is selectively permeable - it does not allow certain substances to enter the cell

to protect the plant cell, to give it or maintain the shape of the cell to prevents excessive uptake of water

made up of cellulose which is a tough substances which helps it stand upright

to provide a liquid medium for chemical reactions to take place

it houses chromosomes which are made of chromatin (DNA and proteins ) IT contains deoxyribonucleic acid (DNA) of organism DNA contains the info that’d determines the organisms inherited characteristic nucleus controls all cell activities

it is the site for respiration energy is released from glucose in the process of respiration this energy produced from respiration is need by the cell to carry out it specific function

used to store substances that can be used by cell aslo functions in waste disposal ad water balance
