What are the organelles found in the cell?
Ans: vacuole, cell wall, plasmondesma, chloroplasts, nucleus, cell membrane
List the structural features of the cells.
Ans: Plant cells have a special structure called cell wall that help it support itself and give its shape. The cell also contain chloroplast that help it make food by absorbing sunlight, with carbon dioxide (CO2) and water, a simple sugar called glucose is made.
What are the functions of these organelles?
Ans:cell membrane - the thin layer of protein and fat that surrounds the cell, but is inside the cell wall. The cell membrane is semipermeable, allowing some substances to pass into the cell and blocking others.
cell wall - a thick, rigid membrane that surrounds a plant cell. This layer of cellulose fiber gives the cell most of its support and structure. The cell wall also bonds with other cell walls to form the structure of the plant.
chlorophyll - chlorophyll is a molecule that can use light energy from sunlight to turn water and carbon dioxide gas into sugar and oxygen. (this process is called photosynthesis). Chlorophyll is magnesium based and is usually green.
chloroplast - an elongated or disc-shaped organelle containing chlorophyll. Photosynthesis (in which energy from sunlight is converted into chemical energy - food) takes place in the chloroplasts.
nucleus - spherical body containing many organelles, including the nucleolus. The nucleus controls many of the functions of the cell (by controlling protein synthesis) and contains DNA (in chromosomes). The nucleus is surrounded by the nuclear membrane
vacuole - a large, membrane-bound space within a plant cell that is filled with fluid. Most plant cells have a single vacuole that takes up much of the cell. It helps maintain the shape of the cell.
Plasmodesmata (singular: plasmodesma) are microscopic channels which traverse the cell walls of plant cells
Why are the functions of organelles important to the living cell?
Ans:The organelles work together to help the cell grow and reproduce.

I have learnt about Plasmodesta
ReplyDeleteBesides learning that the sap of a plant cell is actually a large single vacuole, that is unlike the vacuoles animal cells, I also learnt more about the structure and the components of plant cells based on the diagrams.
ReplyDeleteI've learnt about Plasmodesmata after reading their work which is quite need and organised and answers the questions. All except the last is complete.
ReplyDeleteI learnt about the Plasmodesta, which is new to me and have learned more about the different parts of plant cell. Their work is organized, making it easy to read and understand.
ReplyDeleteI have learnt about Plasmodesta after reading this group's work.I have also learnt about more functions of the parts of the cell.
ReplyDeletewant some more information and it's a really nice to see like this..
