Answer:
Q - 1 Tissues are a group of cells working together and performing a particular function. Tissues are important as they form the organs, which in turn form the organ system which form an organism.
Q - 2 strengthening tissue in a plant, formed from cells with thickened, typically lignified, walls.
Q - 3 Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. Epithelial cells may be squamous, cuboidal, or columnar in shape and may be arranged in single or multiple layers.
Q - 4 The shape of the human red blood cell (RBC) is known to be a biconcave disc. The experiments in this paper identify some of the underlying determinates. RBC ghosts were made such that they were spheres in hypo-osmotic solutions and biconcave discs in iso-osmotic solutions
Q - 5 Humans have 23 pairs of chromosomes, for a total of 46 chromosomes.
Q - 6 The ribosome, the protein factory in every living cell, gathers amino acids and assembles them into protein chains to make almost anything the cell needs. A strand of ribonucleic acid, or messenger RNA, is the template
Q - 7 ovum
Q - 8 longest animal cell = neuron
Q - 9 A plasma membrane has subcellular level of organisation and consists of a lipid bilayer and protein molecules. It is a semipermeable, quasifluid structure which maintains the cell integrity.
Q - 10 150,000 to 400,000
1.Tissues are a group of cells working together and performing a particular function. Tissues are important as they form the organs, which in turn form the organ system which form an organism.
2.Sclerenchyma tissue, when mature, is composed of dead cells that have heavily thickened walls containing lignin and a high cellulose content (60%–80%), and serves the function of providing structural support in plants. Sclerenchyma cells possess two types of cell walls: primary and secondary walls. 3.Epithelium is one of only 4 types of human body tissues. Like all types, it is formed by cells within an extracellular matrix (ECM).
The cells in this tissue are tightly packed within a thin ECM. Forming sheets that cover the internal and external body surfaces (surface epithelium) and secreting organs (glandular epithelium). Functions of epithelial tissue are secretion, protection, absorption, transportation and special sensory receptive. 4.The shape of the human red blood cell (RBC) is known to be a biconcave disc. 5.Humans have 23 pairs of chromosomes, for a total of 46 chromosomes 6.The ribosome, the protein factory in every living cell, gathers amino acids and assembles them into protein chains to make almost anything the cell needs. A strand of ribonucleic acid, or messenger RNA, is the template. 7.The largest cell is ovum in the human body. The ovum also called egg cell is the reproductive cell in the female body. Ovum is 20 times bigger than the sperm cells and has a diameter of about 0.1 mm. 8.neuron 9.A plasma membrane has subcellular level of organisation and consists of a lipid bilayer and protein molecules. It is a semipermeable, quasifluid structure which maintains the cell integrity 10.The normal number of platelets in the blood is 150,000 to 400,000 platelets per microliter (mcL) or 150 to 400 × 109/L.
