B Laminaria is a brown algae. Food is stored as complex carbohydrate which may be in the form of laminarin or manitol. - The vegetative cells have a cellulosic wall usually covered on the outside by a gelatinous coating of alginic acid.

Which of the following structure is not found in a prokaryotic cell?
1 Plasma membrane
2 Nuclear envelope
3 Ribosome
4 Mesosome
Explanation:
B The nuclear envelope, also known as the nuclear membrane, is made up of two lipid bilayer membrane that in eukaryotic cells surround the nucleus, this nucleus envelope absent in prokaryote and genetic material is naked, laying in cytoplasm. They however possess ribosome, mesosome and plasma membrane. In prokaryote mesosome is a convoluted membranous structure formed in a prokaryote cell. By the invagination of plasma membrane. These extention help in the synthesis of the cell wall and replication of DNA. They help in equal distribution of chromosome into the daughter cells. Mesosomes helps in secretion process as well as bacterial respiration.

Which of the following is found in animal cell?
1 Plasmodesmata
2 \(80 \mathrm{~S}\) ribosomes
3 Centriole
4 All of these
Explanation:
C Centrioles are small cylindrical, cellular structures found in eukaryotic cells (Animal cells). They play vital role in cell division and are essential components of the centrosome. Centrosomes are regions of the cell where microtubules are organized, and they serves as important centre for cell division.

Which is the largest body cell?
1 Neurons
2 RBCs
3 Osteocytes
4 Sperms
Explanation:
A Nerve cells or Neurons are the longest body cells. These cells make up the nervous system of our body. These cells are therefore found in the brain and the spinal cord.
