Question

Name any five part of plant cell and prively state one function each

Answer 1

Answer:

1. Cell Wall: Present only in plant cells. Made of organic compound called cellulose. Provides structural strength and rigidity to the plants.

2.Chloroplasts: Plastids containing chlorophyll as well as other yellow and orange pigments. External structure is like that of mitochondria. Consists of numerous membrane layers embedded in a material called stroma. Helps mainly in photosynthesis. Has its own DNA and ribosomes, and can make some of its own proteins.

3. Dictyosomes (Golgi Apparatus): Underdeveloped in plant cells as compared to animal cells. Mainly helps in the storage, modification and packaging of materials synthesized near the ER (Endoplasmic Reticulum). Also helps in synthesis of complex sugars from simple sugars and in the formation of lysosomes.

4. Ribosomes: Non-membranous cell organelles present in every active cell- prokaryotes or eukaryotes, and is the manufacturing site of proteins.

5. Vacuoles: Much more important and developed in plant cells than in animal cells. In animal cells, vacuoles are very small but in plant cells, they occupy 50% to 90% of the cell volume. They contain substances important in the life of the plant cells: amino acids, sugars, various organic acids and some proteins. They are also filled with cell sap and provide turgidity and rigidity to the plant cell. Vacuole membrane is called the tonoplast.

Here is your answer. Hope it helps! :)

Answer 2

1. Cell wall: this additional layer surrounding the cell membrane is required plants for protection plant cell need protection against variations in temperature high wind speed atmospheric pressure.

2. Nucleus: nucleus is the most important structure in a Cell IT act like a control centre of the cell and it also has thread like chromosomes 20 carry genes and help in the transfer of characters from the parent to the offspring

3. Cytoplasm: cytoplasm is a jelly like substance present between the cell membrane and the nucleus various other components or organelles of cell are present in the cytoplasm.

4. Mitochondria: Mitochondria generate most of the chemical energy needed to power the cell's biochemical reactions also know as 'Power House of cell'

5. Cell Membrane: The cell membrane is a semi-permeable membrane, that allows the transmission of a very few molecules across it.
