c. oxygen
4.
a. photosynthesis -the process by which green plants turn carbon dioxide and water into food using energy from sunlight
b. the primary body cavity of most invertebrates, containing circulatory fluid.
c. group of cells that work together is called tissue.
5. The five-kingdom system of classification for living organisms, including the prokaryotic Monera and the eukaryotic Protista, Fungi, Plantae and Animalia is complicated by the discovery of archaebacteria.
6 .A virus is made up of a DNA or RNA genome inside a protein shell called a capsid.
7.Carolus Linnaeus is the ‘ Father of taxonomy ’
8.Apical meristem is present at the growing tips of stems and roots and increases the length of the stem and the root.
9.a.Xylem transports only minerals and waters from the roots. Phloem transports food materials that are prepared by the green parts of the plants to other parts of the plant. ... Xylem is the dead tissues at maturity, but no cell contents. Phloem is the living tissue, but not with the nucleus
b. Amphibians
1 They can live both on land and in water.
2.Body of amphibians is covered with slimy- slippery skin.
3.They breathe through the lungs and skin.
Pisces
1 . They live in water
2 Their body is covered with scales.
3 They breathe through gills.
10.penicillin
11 a. The term “biodiversity” refers to the variety of living organisms. Biodiversity brings together the different species and forms of life (animal, plant, entomological and other) and their variability, that is to say, their dynamics of evolution in their ecosystems
b. The three basic bacterial shapes are coccus (spherical), bacillus (rod-shaped), and spiral (twisted)
c. Though there are many more good bacteria than bad, some bacteria are harmful. If you consume or come in contact with harmful bacteria, they may reproduce in your body and release toxins that can damage your body's tissues and make you feel ill.
12a.Mersitematic tissues are then classified into: Apical, intercalary, and lateral meristem. 12)b.Permanent are classified into Simple permanent and Complex Permanent. permanent tissue derived from meristematic tissue and comprising of non dividing cells .
12 c. tissues join together to form organ. and organs perform various activities for the body. Tissue present on the outer layer of the body provides protection. skeletal tissues provide strength.
d. The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste and other unwanted materials. The primary function of the lymphatic system is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body.
13.The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.
