what was the difference between gymnosperms and angiosperms?

The key difference between angiosperms and gymnosperms is how their seeds are developed. The seeds of angiosperms develop in the ovaries of flowers and are surrounded by a protective fruit. ... Gymnosperm seeds are usually formed in unisexual cones, known as strobili, and the plants lack fruits and flowers.

Animal Cells versus Plant Cells Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.

And they are made up of a heterogeneous group of plants characterized by the production of naked seeds. ... Most gymnosperms lack vessels in their xylem (unlike flowering plants which have both vessels and tracheids), except for the gnetophytes, which have vessels.

['All angiosperms have flowers at some stage in their life. ... ', 'Angiosperms have small pollen grains that spread genetic information from flower to flower. ... ', 'All angiosperms have stamens. ... ', 'Angiosperms have much smaller female reproductive parts than non-flowering plants, allowing them to produce seeds more quickly.']

Compared to humans, plants have a single large vacuole, which is centrally located. ... This is the most significant difference among plants and humans because humans do not contain chloroplasts. Plants are capable of making their own food, while humans depend on other living things for survival.

Major structural differences between a plant and an animal cell include: Plant cells have a cell wall, but animals cells do not. Cell walls provide support and give shape to plants. Plant cells have chloroplasts, but animal cells do not.

Seed plants that flower are called angiosperms, and their seeds grow inside tissue that is part of the plants' ovaries, more commonly called fruit. Conifers are gymnosperms, and their seeds grow naked, often on the scales of a cone, instead of encased in fruit.

--Angiosperms are a taxonomic class of plants in which the mature seed is surrounded by the ovule (think of an apple). ... Angiosperms are trees have broad leaves that usually change color and die every autumn. Oaks, maples and dogwoods are examples of deciduous trees.

Ferns are plants that do not bear flowers. They do not have any seeds as well. In this regard, their mode of reproduction is through spores. Gymnosperms on the other hand have seeds, although they are not put inside an ovary.

The polyphyletic origin of angiosperms is further supported by the fact that primitive orders of both the monocots and dicots do not show any close relationship in their characters. Thus fossil records suggest that angiosperms, as a group, are monophyletic, and their families or groups of families are polyphyletic.

Angiosperms, also called flowering plants, have seeds that are enclosed within an ovary (usually a fruit), while gymnosperms have no flowers or fruits, and have unenclosed or “naked” seeds on the surface of scales or leaves.

The Difference are as Follows: 1) Plant cell always have cell wall while animal cells do not. 3) Plant cell do not have centrioles (used for formation of spindle fibres) while animals have. 4) Plant cell have a large centralised vacuole while animal cell have few small scattered vacuole.

These seed plants fall into two groups, angiosperms and gymnosperms. Angiosperms are the flowering plants. Their seeds develop inside a female reproductive part of the flower, called the ovary, which usually ripens into a protective FRUIT.

[' Angiosperms have covered seeds.', ' They undergo double fertilization process to produce zygote and endosperm.', ' Angiosperms have distinguished male and female sex organs i.e.stamen and carpel respectively.', ' Angiosperms are flowering plants that have colorful flowers with them.']

As nouns the difference between plant and seedling is that plant is an organism that is not an animal, especially an organism capable of photosynthesis typically a small or herbaceous organism of this kind, rather than a tree while seedling is (botany) a young plant grown from seed.

Angiosperms are flowering plants whose seeds are surrounded by fruit. Vascular plants are plants with tubes to carry nutrients and water throughout the plant. Nonvascular plants are plants without transport tubes to carry water and nutrients throughout the plant.

Angiosperms are unique plants because they produce protected seeds. This alternation of generations in flowering plants, such as oak trees and wildflowers, means that there are multicellular stages that are haploid and diploid.
