Answer 1

Answer:

1:Paleontologists recognize fossils based on their shape, their structure, and sometimes the material they are made of. Since fossils are the remains of ancient life, paleontologists study the shape, structure, and materials of living things today.

2:fossil plants

Paleobotany is the study of fossil plants. The oldest widely occurring fossils are various forms of calcareous algae that apparently lived in shallow seas, although some may have lived in freshwater.

3Histology. It is the study of different tissues present in the plant body.

ii) Anatomy. It deals with the study of gross internal details of plant organs like root, stem, leaf, flower etc.

Cytology (or) Cell Biology. ...

Embryology. ...

Palynology. ...

Plant Taxonomy. ...

Plant Ecology. ...

Palaeobotany.

4.Vascular cryptogam is an old botanical phrase and it refers to those vascular plants that do not make seeds. Thus, cryptogam refers to the production of a separate, usually very small, archegoniate gametophyte. These are well represented in the fossil record.

Thus, vascular cryptogams are pteridophytes.

5:Vrikshayurveda is an ancient text of India that tells us about how to grow trees and how to grow them better. It is a source text on arboreal medicine from ancient India. It is said to be written by around 400 BC by Salihotra.

6:Maharshi Parashar was a great poet of Rajasthan born in Ajmer. His famous work is Krishi Parasar, which is a book on agriculture. He wrote a meaningful shlok with the following meaning: 'grains come from crops and crops never come without farming hence effort should be made for agriculture leaving everything aside

Answer 2

Answer:

1. Paleontology, also spelled palaeontology or palæontology, is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene epoch. It includes the study of fossils to classify organisms and study their interactions with each other and their environments.
2. Paleobotany, which is also spelled as palaeobotany, is the branch of botany dealing with the recovery and identification of plant remains from geological contexts, and their use for the biological reconstruction of past environments (paleogeography), and the evolutionary history of plants, with a bearing upon the evolution of life in general. A synonym is paleophytology.
3. Phycology.
4. Pteridophytes are vascular cryptogams, widely distributed all over the world. They are taxonomically intermediate between bryophytes and phanerogams. They possess a combination of features that are absent in bryophytes and phanerogams.
5. Vrikshayurveda is the ancient Indian science of plant life, a body of knowledge that has been systematically compiled in the form of 325 Sanskrit slokas in a text named VRIKSHAYURVEDA by Surapala approximately 1000 years ago.
6. Krishi Parasaram deals with Weeds and seeds.
