Answer 1

Answer:g

A)

1. Venation is the phenomenon of arrangement of veins in the lamina of the leaf surface. It is of three types, reticulate, parallel and furcate venation. In reticulate venation, veins form the network like structure. For example, leaves of dicot plants.

2. a) the sweet pea (Lathyrus odoratus)

b) Barberry (Berberis vulgaris)

c) Venus flytrap

3. There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus.

4. a) Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant.

Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.

b) Simple leaves have single leaf blade or lamina while compound leaves have smaller and separate leaf blades called leaflets.

The base of a simple leaf contains stipules, but in compound leaf, the stipules are found at the base of the leaf, but other additional structures are absent.

c) Monocots can be defined as the plants with the seed having only one cotyledon, and the plant is called as monocotyledons, while plants with the seed having two cotyledons are called as dicots, and the plant is called as dicotyledons

B)

1. Venus flytrap

2. petiole

3. phyllotaxy

4. flower

5. stem

sorry can't figure out the last one

try looking up all the definitions of the words and try figuring out the odd one out
