Question

Aim: to study the characteristics of spirogyra agaricus moss fern pinus and an angiosperm plant and give two features of group they belong to

Answer 1

Spirogyra
Division Thallophyta
Thalllophytes are predominantly aquatic
Their body consists of an undifferentiated mass called the thallus

Agaricus
Kingdom Mycota or Fungi
These are Saphrophytic or Parasitic organisms that are achlorphyllus
Their body consists of strand like structures called hyphae which form the body network called the mycelium

Cell wall is made up of chitin and cellulose, a mixture called fungal cellulose

Moss
Division Bryophyta
Bryophytes are also called the amphibians of the plant kingdom because they can live on land but need water to reproduce
They have poorly differentiated body strutures like root like rhizoids, a stalk with capsules and the leaves

Fern
Division Pteridophyta
These have well differentiated vascular tissue
These have Very well differentiated body structures but have hidden or conspicuous reproductive organs

Pinus
Division Gymnospermae
Gymnosperms reproduce through well designed reproductive organs that are not hidden. They are spermatophytes
They reproduce through uncovered seeds/ naked seeds

Mustard Plant
Division Angiospermae
Angiosperms are again spermatophytes or phanerogams .
They reproduce through seeds covered by fruits which are structures that arise from the ovary.
Their seeds may have one or two cotyledons

Hope this helps!
