As i told in the class, student should be able to draw and label the organelles for plant cell and animal cell. So, based on the diagram above state the features and its fuction respectively. (10 marks)
based on the diagram above state the features and its fuction respectively. -cell wall:gives shape to a plant cell and provides mechanical support for the plant cell. -cell membrane:regulates the movement of substances into and out of the cytoplasm. -cytoplasm:provides substances obtained from the external environment to the organelles. -nucleus:controls all the activities which take place in the cell. -vacuole:help to regulate water balance in these in organisms. :acts as a storage place in a cell. -mitochondria:release energy when food substances such as glucose are broken down with the help of enzymes present in the mitochondria -ribosomes:synthesis of proteins such as enzymes take place in the ribosomes. -rough e.r:transports proteins made by ribosomes. -smooth e.r:synthesis of lipids and detoxification of drugs and poison. golgi apparatus:processing,packaging,and transporting centre of carbohydrates,proteins,phospholipid,and glycoprotein. -lysosomes:eliminate worn out mithocondria and other damaged organelles to enable a cell to renew itself. -chloroplasts:traps sunlight and converts light energy into chemical energy during photosynthesis.
plasma membrane-separates a cell from its external enviroment. cell wall-provides support and protection for the cell cytoplasm-provides substances obtained from the external environment to the organelles. nucleus-control all the cell activities RER-synthesis and transport protiens made by ribosomes SER-synthesis and transport lipids golgi apparatus-receive protiens from the RER,then modifies and combined the protiens and carbohydrates to form glyco-protiens chloroplast-carry out photosynthesis in the chlorophyll of the grana vacuole-generally for storage,digestion and waste removal
state the features and its fuction respectively. (10 marks)
1.cell wall -is a rigid outer layer that surrounds the plasma membrane of plant cell. function:protect the plant cell from rupturing due to the excessive intake of water. 2.cytoplasm -is the region between the nucleus and the plasma membrane. function:provides substances obtained from the external environment to the organelles 3.nucleus -contains the nucleoplasm and a dark spherical structure called the nucleolus. function:controls all the activities which take place in the cell. 4.vacuole -fluid-filled sac which is surrounded by tonoplast, a semi-permeable membrane. function:acts as storage place in a cell. 5.mitochondria -are involved in cellular respiration function:release energy when food substances such as glucose are broken down with the help of enzymes present in the mitochondria. 6.lysosomes -membrane-bound sacs that contain hydrolytic enzymes. function:digest bacteria by breaking down the bacterial cell wall. 7.chloroplast -the membranous structures in the chloroplast contain the green pigment chlorophyll. function:traps sunlight and converts light energy into chemical energy during photosynthesis.
