<u>Gymnosperms and Angiosperms-</u>
Gymnosperms and angiosperms evolved seeds and pollen grains allowing them to live and reproduce in drier habitats than bryophytes and seedless vascular plants.
<u>Properties of gymnosperms and angiosperms-</u>
Gymnosperms are plants which bear seeds without fruits or without any outer coverings. These plants also do not produce flowers. Most plants under this group have needle-shaped leaves. This is an adaptation as these plants grow in colder conditions. Gymnosperms. These plants produce pollen without bearing flowers. Angiosperms are found in almost all climatic conditions. These plants bear flowers and produce seeds that are enclosed inside a fruit or inside an ovary. The seeds of angiosperms have a single cotyledon.

Answer:
There are seven currently recognized families of bees: Apidae, Megachilidae, Halictidae, Andrenidae, Colletidae, Melittidae, and Stenotritidae. The largest one, Apidae, includes our well-known honey bees and bumble bees. However, these bees make up only a fraction of total bee diversity even within their own family.
Explanation:
Diffusion is the spontaneous movement of substances from a region of high concentration to a region of low concentration.
Osmosis is the passage of water molecules from a high water concentration region through a selectively permeable membrane to a low water concentration region.
In diffusion, selectively permeable membrane is neither required nor involved while in osmosis, it is involved.
