Plant Cell Structure
Karten in diesem Stapel (15)
- 1What type of cells are plant cells?eukaryotic cells?
- 2What's a leaf palisade cells role?carry out photosynthesis
- 3What are the main features of a leaf palisade cell?Long, thin cells form continuous layers for maximum absorption of sunlight.
Numerous chloroplasts that can move to be in the best position for absorption. Vacuole pushing chloroplasts to the edge - 4What are chloroplasts function?carry out photosynthesis
- 5What are the typical shape of chloroplasts and what are their main features?Typically disc-shaped and include the chloroplasts envelope, the grana and the stroma.
- 6Describe the chloroplasts envelope.Double plasma membrane surrounding organelles, it is highly specific on what it allows to enter the cell or not.
- 7Describe the grana.Stacks of up to 100 structures called thylakoids, within this is chlorophyll (photosynthetic pigment). This is where the first stage of photosynthesis takes place.
- 8Describe the stroma.fluid-filled structure that is where the second stage of photosynthesis takes place. Within the stroma are other structures, such as starch grains.
- 9How are the chloroplasts adapted for their function?Large surface area for the attachment of chlorophyll and fluid of the stroma possess enzymes needed for the second stage of photosynthesis.
- 10What do chloroplasts contain?DNA and ribosomes for the easy manufacture of proteins (enzymes) needed for photosynthesis.
- 11Describe the cell wall.Consists of microfibrils of the polysaccharide cellulose embedded in a matrix. This adds to the strenght of the wall.
- 12Cell walls have the following features..-consist of a number of polysaccharides, -middle lamella marking the boundary between adjacent cells,
- 13The functions of the cellulose cell wall are to:-give mechanical strength to the plant, -provide strength in order for the cell to stop bursting, -allow water to pass along it contributing to the movement of water through a plant.
- 14What are some differences of plant and animal cells? First plant cells..-cellulose cell wall
-vacuole filled with sap
-chloroplasts are present
-starch grains are used for storage - 15What are some differences of plant and animal cells? Now animal cells..-no chloroplasts present
-only a cell surface membrane
-if vacuoles are present, small and scattered about the cell
-glycogen granules used for storage
