The cell wall's main function is physical support. But the study reveals more points as. 1 Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast. Plants are the basis of all life on Earth. They are classified as the producers of the world Name: _____ Cell #2 H.W. due September 22nd, 2016 Period: _____ The extra sugar that the plant does not use is stored as Chloroplasts are the food producers of the cell. The organelles are only found in plant cells and some protists such as algae In plant cells, chloroplasts may be moved around with the stream, possibly to a position of optimum light absorption for photosynthesis. The rate of motion is usually affected by light exposure, temperature, and pH levels. The optimal pH at which cytoplasmic streaming is highest, is achieved at neutral pH and decreases at both low and high pH These functions greatly affect the life cycle and sustainability of every plant cell. Some of these functions are the removal of unwanted molecules. Dead or damaged cell organelles are removed from the cell to keep it healthy
The vacuole is a type of organelle present in eukaryotic cells. It is a sac surrounded by a single membrane called a tonoplast. The membrane holds fluid called cell sap, which is composed of water and other substances. Vacuoles serve many functions, such as supporting the cell wall in plant cells An analogy of the plant cell is a school. The brick on the outside on the cell is like the cell wall because it supports the structure and it gives protction, the doors to enter and exit the school are like the cell membrane because it lets people go in and out of the school, the cytoplasm is like the air around the student because it fills the city so people can breath and the cytoplasm fills. Plants, as every 3rd grader learns, use chloroplasts to generate high energy electrons (in the form of NADPH) which are then used to make ATP through oxidative phosphorlation Plastids are plant organelles that function in nutrient synthesis and storage. These double-membrane, cytoplasmic structures have their own DNA and replicate independently of the cell. Plastids develop from immature cells called proplastids that mature into chloroplasts, chromoplasts, gerontoplasts, and leucoplasts
