What structure do angiosperms have and gymnosperms lack srobiliconesfruitvascular tissue?
Angiosperms possess flowers and fruits, which are reproductive structures that facilitate pollination and seed dispersal. In contrast, gymnosperms do not have flowers or fruits; instead, they reproduce using cones. Both groups have vascular tissue, but the defining feature that distinguishes angiosperms from gymnosperms is the presence of flowers and fruit.
What else can I help you with?
Why root pressure is absent in gymnosperms?
Root pressure is absent in gymnosperms because they lack vessels in their xylem tissue. Vessels in angiosperms help create positive pressure when water is actively transported, resulting in root pressure. Gymnosperms rely on a combination of capillary action and cohesion-tension to move water up the plant.
What is the 3n nutritive tissue in the seed of angiosperms called?
the triploid The endosperm is a nutritive tissue which nourishes the developing embryo. The endosperm in angiosperm is triploid (3n) and it is a post - fertilization structure.
Do all plants have vascular tissue and produce seed?
No, not all plants have vascular tissue. Vascular plants have xylem and phloem to transport water and nutrients. Additionally, not all plants produce seeds. Seed-producing plants are divided into gymnosperms (like conifers) and angiosperms (flowering plants).
The highly nutritious tissue found in the seeds of angiosperms?
endosperm
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.
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 are the main characteristics used to differentiate between the angiosperms and gymnosperms?
Angiosperms are characterized by enclosed seeds within a fruit, while gymnosperms have exposed seeds on the surface of scales or cones. Angiosperms have flowers for reproduction, while gymnosperms have cones. Additionally, angiosperms have vessels in their xylem, while gymnosperms have tracheids. These are the main characteristics used to differentiate between angiosperms and gymnosperms.
What are 4 example of vascular?
There are only three (not four) groups of vascular plants. The vascular tissue is used to transport nutrients and water through the plant. There is seedless vascular plants, angiosperms, and gymnosperms.
Are sunflowers angiosperms or gymnosperms?
The flowering plants (angiosperms) are also known as Angiospermae or Magnoliophyta. There are more than 250,000 of these seed producing plants. YES, sunflowers are included.Characteristics of Angiosperms:Flowers (the thing that sets angiosperms apart from all others)Stamens (specialized to attract pollinators & modified to prevent self-fertilization)Smaller sized pollen (than the gymnosperms)Closed carpel (cuts down on self-fertilization and increases genetic variablity)Smaller sized "egg" (than the gymnosperms)Endosperm (nutritive tissue for embryo, cotyledons & seedling)The flowering plants (angiosperms) are also known as Angiospermae or Magnoliophyta.

What are the diversity of classification of plantae?
Plants are classified into division based on characteristics like presence of vascular tissue, presence of seeds, and type of reproductive structures. Some main plant divisions include bryophytes (mosses), pteridophytes (ferns), gymnosperms (cone-bearing plants), and angiosperms (flowering plants). Within these divisions, plants are further classified into various families, genera, and species.
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.
What tissue is responsible for growth in angiosperms?
Meristematic tissue is responsible for growth in angiosperms. It is found in regions of the plant where growth occurs and contains cells that continuously divide and differentiate into various types of plant tissues.
Two features that angiosperms and their gymnosperm ancestors have in common are?
The presence of seeds and vascular tissue
