Monoecious plants Dioecious plants Angiosperms Gymnosperms A. has megasporangiate and microsporangiate flowers on the same plant B. has megasporangiate and microsporangiate flowers on different plants C. produce flowers and fruits D. produce seeds that are not protected by the ovary

Answer:monoecious-

A. has megasporangiate and microsporangiate flowers on the same plant

Dioecious - B. has megasporangiate and microsporangiate flowers on different plants.

Angiosperm-C. produce flowers and fruits

Gymnosperm - D. produce seeds that are not protected by the ovary

Explanation:

Monoecious plant are plant that have both male and female part or sex organ are located on the same plant example is cowpea

Dioecious are plant that have male and female gametes or organ are locate on different plants example is pawpaw

Angiosperm are called flowering plant. They have both fruits and seed. The ovule develops into seed while the ovary develops into the fruits. They are both unisexual and bisexual example is peas

Gymnosperms are non flowering plant. They have seeds but no fruits. They are unisexual example is pine

The question is incomplete. The correct question is:

Match the following with what describes it best:

A. has megasporangiate and microsporangiate flowers on the same plant

B. has megasporangiate and microsporangiate flowers on different plants

C. produce flowers and fruits

D. produce seeds that are not protected by the ovary

Answer:

Monoecious plant - A

Dioecious plant - B

Angiosperms - C

Gymnosperms - D

Explanation:

Monoecious plants are referred to as bisexual plants, that is, they have both male and female reproductive organ in the same plant while dioecious plants are also called as unisexual plants, that is, each plants with have male reproductive part or female reproductive parts.

Angiosperms and Gymnosperms are two major groups of vascular seed plants.

Gymnosperms are plants which produce naked seeds. The seeds unenclosed or are not enclosed in the fruits. Gymnosperms are majorly perenial.

Angiosperms are flowering plants. They produce seeds enclosed within an ovary (majorly A fruit). Angiosperms are majorly non-perenial.
