1.WHAT IS ANABOLISM?
ANS: Anabolism is a metabolic process in which simple substances
combine to form complex molecules. It requires energy and is
responsible for growth, repair, and storage in the body. Examples
include protein synthesis and formation of glycogen.
2.WHAT IS CATABOLISM?
ANS: Catabolism is the metabolic process in which complex molecules
are broken down into simpler substances. It releases energy and helps
provide fuel for body activities. Examples include digestion of food and
breakdown of glucose.
3. CRITERIA OF CLASSIFICATION OF TAXONOMY?
ANS: Taxonomy classifies organisms based on several criteria to group
similar organisms together. The main criteria include:
Morphology: External structure and form of organisms
Anatomy: Internal structure
Cell structure: Prokaryotic or eukaryotic, cell organelles
Genetic makeup: DNA and hereditary features
Mode of nutrition: Autotrophic or heterotrophic
Reproduction: Sexual or asexual methods
Evolutionary relationships: Common ancestry and phylogeny
These criteria help scientists organize and identify living organisms
systematically.
4.DIFFERNCE BETWEEN GYMNOSPERM AND ANGIOSPERM?
ANS:
, Feature Gymnosperms Angiosperm
Seeds Naked seeds (not enclosed) Seeds enclosed in fruit
Flowers No flowers Present
Fruits Absent Present
Examples Pine, Cycas Mango, Rose
Fertilization Single fertilization Double fertilization
In short:
Gymnosperms have naked seeds, while angiosperms have seeds inside fruits.
5.WRITE DOWM THE TYPES OF PLANTIE?
ANS: Plants are mainly classified into the following types:
1. Thallophyta – Simple plants without true roots, stems, or leaves (e.g.,
algae)
2. Bryophyta – Small plants, need water for reproduction (e.g., moss)
3. Pteridophyta – Have roots, stems, and leaves but no seeds (e.g., fern)
4. Gymnosperms – Seed-producing plants with naked seeds (e.g., pine)
5. Angiosperms – Flowering plants with seeds inside fruits (e.g., mango, rose)
In short:
Plants are divided based on their structure and reproduction into five main.
6.DISCUSS THE CHARECTERISTIS OF ANGIOSPERM,GYMNOSPERM,
PTERIDOPHYTA,BRYOPHYTA?
ANS: Angiosperms
Characteristics:
Produce flowers and fruits
Seeds are enclosed inside fruits
Show double fertilization
Well-developed roots, stems, and leaves
Advanced vascular system (xylem & phloem)
