Give reasons
1. Mitochondria is called energy house of the cell
2. Lysosomes are termed as the suicide bags of the cell
3. Organisms like fungus can withstand hypertonic solutions.
4. The number of chromosomes in the reproductive cells are half in number that of the
vegetative cells.
5. Plasma membrane is called selectively permeable membrane.
Answers
Answer:
1. Because it stores energy of the body.
2. Because when they are hungry they eat their own cells .
4. Because of conversion of dublet into haploid or there is a difference of sexual and asexual reproduction.
5. Because it secrets seleted organs .
Answer:
1.Mitochondria are tiny organelles inside cells that are involved in releasing energy from food.
This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.
2.When cell gets damaged,lysosomes may bursts and the enzymes digest their own cell. this is the reason why they are called sucidal bag.
3.pressure exerting inside fungus is less than outer pressure.
4.becoz in reproduction the cell are dividided to form a zygot .
5.The plasma membrane is selectively permeable; hydrophobic molecules and small polar molecules can diffuse through the lipid layer, but ions and large polar molecules cannot.
Ions are often used in secondary transport systems because they generate an electrochemicalgradient.
