animal and plant cells

• both eukaryotes cells
• they are multicellular, they contain multiple cells. so when there cells divide they are normally growing or replacing dead cells
• both cells surrounded by cell membranes
• cell membrane

  control which substances can pass in and out of the cell
• both contain a nucleus
• nucleus

  contains the genetic material/ DNA of the cell
• both filled with the gel like substance cytoplasm
• cytoplasm

  where chemical reactions take place
• both contain a mitocondria
• mitocondria

  provides cell with the energy they need to function
• both contain ribosomes
• ribosomes

  site of protein synthesis
• plant cells have a ridged cell wall around the whole cell
• the ridged cell wall (made from cellulose) of a plant cell is very strong and provides support and structure which is important as if too much water entered the cell, it would burst
• plant cells contain a permanent vacuole which takes up most of the space
• permeant vacuole

  contains cell sap (mixture of sugar, salts, water)
• plants contain chloroplast
• chloroplast

  where photosensitise happens
• chloroplast contains a green substance called chlorophyll which absorbs light for photosynthesis
• energy is released in mitocondria by respiration
• the nucleus controls the actives of the cell. the cytoplasm is a jelly-like substance in which chemical reactions take place. the cell membrane holds the cytoplasm together and controls which substances pass into and out the cell. the cell membrane selectively allows substances into and out of the cell. most cells contain mitochondria (for respiration). the function on mitocondria is the release energy, this happens by respiration. most cells contain ribosomes (for protein synthesis). the function of ribosomes is to make proteins
• plant cells also contain a cell wall to strengthen the cell. cell walls are made from cellulose. the cell wall strengthens the cell. plant cells also contain green substance called chloroplast. chloroplast contains green chlorophyll. chlorophyll absorbs light energy from the sun. plants need light energy for photosynthesis. plant cells also contain permeant vacuole filled cell sap. a permanent vacuole is filled with cell sap. cell sap stores substances dissolved in water and it also helps to support the plant cell
