Question

give two characteristics and one example for each of the following Monocot Dicot Bryophyta Pteridophyta Gymnosperms​

Answer 1

Answer:

MONOCOTS

Embryo with single cotyledon  

Pollen with single furrow or pore  

Flower parts in multiples of three    

Major leaf veins parallel

DICOTS

Embryo with two cotyledons

Pollen with three furrows or pores

Flower parts in multiples of four or five

Major leaf veins reticulated

BRYOPHYTES  

Bryophytes are non-vascular plants.  

The plant body is leafy or thalloid.  

No vascular tissues.

PTERIDOPHYTES

Pteridophytes are vascular plants

The plant body is differentiated into roots, stem and leaves.

Vascular tissues are present.

GYMNOSPERMS:

Sporophyte lifecycle dominant

Vascuar tissue found in all parts of the plant

Needles

Seeds instead of spores (found in cones)

Dioecious (one plant makes both pollen comes (male) and female cones)

Pollination by air/pollinators

Answer 2

MNOCOT:-

(1)fibrous root .

(2)generally paralleld venation .

(3)Eg:banana,wheat

DICOT:-

(1)Tip root.

(2)Generally reticulated venation.

(3)Eg:mango,apple

BRYOPHYTA:-

(1)It called as amphibians.

(2) They live in soil but dependent in water.

(3)Eg:marchantia

PTERIDOPHYTES:-

:-(1)It is used for medical purposes.

:-(1)It is used for medical purposes. (2)it is a terrestrial plant posses vascular tissue.

:-(1)It is used for medical purposes. (2)it is a terrestrial plant posses vascular tissue. (3):fern, salvinia

:-(1)It is used for medical purposes. (2)it is a terrestrial plant posses vascular tissue. (3):fern, salvinia GYMNOSPERM:-

:-(1)It is used for medical purposes. (2)it is a terrestrial plant posses vascular tissue. (3):fern, salvinia GYMNOSPERM:-(1)their sunken stomata help for reduced Water loss.

(2)it produce haploid microspores.

(3) Eg: cycas, pinus
