Answer 1

Answer:

hey bud! here's your answer

Explanation:

Q.1 write a short note on mitochondria

• Mitochondria are known as the powerhouses of the cell.

• They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell.

• The biochemical processes of the cell are known as cellular respiration

Q.2 explain the concept of diffusion

• diffusion is the movement of a fluid from an area of higher concentration to an area of lower concentration.
• ... Diffusion may also be thought of as the movement of particles down a concentration gradient.
• The term "diffusion" comes from the Latin word diffundere, which means "to spread out.

Q.4 write the differences between a plant and animal cells

• Animal Cell Plant Cell
• Cell wall Absent Present (formed of cellulose)
• Shape Round (irregular shape) Rectangular (fixed shape)
• Vacuole One or more small vacuoles (much smaller than plant cells). One, large central vacuole taking up to 90% of cell volume.
• Centrioles Present in all animal cells Only present in lower plant forms (e.g. chlamydomonas)
• Chloroplast Absent Plant cells have chloroplasts to make their own food.
• Plastids Absent Present
• Plasma Membrane Only cell membrane Cell wall and a cell membrane
• Flagella Present in some cells ( e.g. mammalian sperm cells) Present in some cells (e.g. sperm of bryophytes and pteridophytes, cycads and Ginkgo)
• Lysosomes Lysosomes occur in cytoplasm. Lysosomes usually not evident.
• Cilia Present Most plant cells do not contain cilia.
