What are 3 characteristics of an angiosperm?
Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds.
What are the characteristics of magnoliophyta?
The characteristic features of the phylum (division) of Magnoliophyta are: (1) ovules are enclosed in a more or less completely closed cavity formed by one or by several to many separate or united carpels; (2) pollen grains are deposited not directly on the micropyle of the ovule but on the stigmatic surface, which is …
What are the characteristics of a angiosperm?
All angiosperms are comprised of stamens which are the reproductive structures of the flowers. They produce the pollen grains that carry the hereditary information. The carpels enclose developing seeds that may turn into a fruit. The production of the endosperm is one of the greatest advantages of angiosperms.
What is unique about Anthophyta?

Are Magnoliophyta and Angiospermophyta the same?
Anthophyta (Angiospermophyta; Magnoliophyta) A phylum comprising the flowering plants (angiosperms). The gametes are produced within flowers and the ovules (and the seeds into which they develop) are enclosed in a carpel (compare Coniferophyta). The angiosperms are the dominant plant forms of the present day.

What characteristics define plants of the division Cycadophyta?
Cycadophyta (cycads) A division of gymnosperms comprising plants with leaves and habit similar to those of palm trees, although some species are quite small. Cycads are dioecious, and most bear large, coloured, female or male cones. Pollen grains have motile spermatozoa within them, which is a very primitive feature.
Mengapa Gymnospermae disebut tumbuhan berbiji terbuka?
Gymnospermae disebut tumbuhan berbiji terbuka karena bakal bijinya tidak tertutup oleh daun buah. Gymnospermae umumnya berupa pohon besar yang batangnya terdapat kambium sehingga dapat membesar dan mempunyai akar tunggal. Alat perkembangbiakan gymnospermae berupa strobilus yang terdiri atas dua yaitu strobilus jantan dan strobilus betina.
Bagaimana perkembangannya tumbuhan angiospermae?

Apa perbedaan angiospermae dan Gymnospermae?
