Which structure is found in a angiosperms but not gymnosperms?
Flowers are a structure found in angiosperms but not gymnosperms. Flowers are reproductive structures that produce seeds enclosed within a fruit, a unique feature of angiosperms. Gymnosperms, on the other hand, have naked seeds that are not enclosed within a fruit.
What do angiosperms produce?
Angiosperms produce flowers, which contain reproductive structures called ovaries that develop into fruits containing seeds. Fruits serve as a means of seed dispersal by attracting animals to eat and spread the seeds.
Which of the following is a characteristic of angiosperms?
One characteristic of angiosperms is that they produce seeds enclosed within a fruit. This distinguishes them from gymnosperms, which have naked seeds. Angiosperms also have flowers, which are reproductive structures that facilitate pollination and seed production.
What two characteristics do all angiosperms share?
Seeds are enclosed in fruits. Leaves are usually broad and flat. Flowers are presentbut cones are absent. Fertilization Is double. Angiosperms are divided into two major groups .... 1. Monocotyledons 2. Dicotyledons In angiosperms, the reproductive structures are located in the flower, which consists of highly modified leaves.
What are the two types of seed plant?
The two types of seed plants are gymnosperms and angiosperms. Gymnosperms include conifers, such as pine trees, which have naked seeds not enclosed in a fruit. Angiosperms are flowering plants that produce seeds enclosed within a fruit.
Do gymnosperms share either of the two characteristics with angiosperms?
Yes, both gymnosperms and angiosperms are seed-producing plants. However, gymnosperms do not produce flowers, which is a characteristic unique to angiosperms.
What structures do angiosperms use for reproduction?
flower

What structures do angiosperms have and gymnosperm lack?
An enclosed ovary
What is a unique feature of ferns in comparison with angiosperms?
Ferns lack the flowers or seeds of the angiosperms. Instead they reproduce by forming spores in two phases, the sporophytic and a gametophytic phase. The second, gametophytic, phase is actually a free-living organism, not a seed.
What do Angiosperms use as a temporary reproductive structure not found in any other group of plants?
Angiosperms use flowers as a temporary reproductive structure, a unique characteristic not found in any other group of plants. Flowers contain the reproductive organs needed for pollination and seed formation, making them essential for sexual reproduction in angiosperms.
What is it that makes gymnosperms and angiosperm unique?
Gymnosperms are non-flowering plants and are in phylum Coniferophyta (also known as Pinophyta). Instead of flowers, they have cones which evolved from reproductive structures called scales. Angiosperms are flowering plants and are in phylum Anthophyta (also known as Magnoliophyta). They are divided into two major groups, monocots and dicots. The reproductive structures are found in the flower parts.
Endosperm tissue is unique to which of these groups?
Endosperm tissue is unique to flowering plants, or angiosperms. Made up mostly of starch, it surrounds a seed and nourishes it.
