Why gymnosperm doesn't bear true fruit?
Gymnosperms do not bear true fruit because they have naked seeds that are not enclosed within a fruit structure. Unlike angiosperms, which develop flowers and fruits as reproductive structures, gymnosperms produce seeds on the surfaces of cones or other structures. The term "gymnosperm" itself means "naked seed," reflecting this characteristic. Consequently, their reproductive strategy relies on the exposure of seeds rather than the protective and dispersive benefits provided by fruit.
As the seeds of an angiosperm develop the ovary change into a?
As the seeds of an angiosperm develop, the ovary changes into a fruit. The ovary wall thickens and matures into the protective and often edible structure that surrounds and protects the seeds. This process helps with seed dispersal and ensures the plant's reproductive success.
What structure do gymnosperms seeds usually develop in?
Gymnosperm seeds typically develop in structures called cones or strobili. Male cones produce pollen, while female cones contain ovules that develop into seeds after fertilization. Unlike angiosperms, gymnosperms do not enclose their seeds in fruit; instead, the seeds often sit exposed on the surface of the cone scales. This reproductive strategy allows gymnosperms to efficiently disperse seeds through wind or other means.
In peas both male and female sex cells?
Peas are monoecious plants, meaning they have both male and female reproductive structures in the same flower. The male reproductive structure is the stamen, which produces pollen containing the sperm cells, while the female reproductive structure is the pistil, which contains the ovary with the ovules that will develop into seeds after fertilization.
What is a cone on a plant?
A cone on a plant is a reproductive structure found primarily in conifers, such as pines and firs. It consists of a central axis with overlapping scales that can contain seeds. Male cones produce pollen, while female cones develop seeds after fertilization. Cones play a crucial role in the plant's reproductive cycle, facilitating the dispersal of seeds.
What is the name of the structure in which cotton seeds develop?

What is the seed bearing structure if gymnosperm called?
The seed bearing structure of gymnosperms is called a cone or a strobilus. It contains the reproductive structures where seeds develop and mature. Gymnosperms do not produce flowers or fruit like angiosperms.
What is the reproductive structure of the mangrove?
The reproductive structure of mangroves typically consists of flowers that produce seeds. These flowers are adapted to be capable of both self-pollination and cross-pollination, ensuring successful reproduction in the challenging environment of the mangrove ecosystem. After pollination, seeds are formed and dispersed to continue the reproductive cycle.
Ovary?
A flower structure that encloses and protects ovules and seeds as they develop.
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 is the structure of a female cone?
The structure of the female cone is the reproductive cone that contains the seeds of the plant. It is also called the Conifer cone.
Are selaginella seedless plants?
Yes, Selaginella have megaspores and microspores not seeds like the naked seeds of Conifers and Cycads and the Seeds of Angiosperms. Selaginella belong to the Clubmoss Group Lycopodiopsida see related link.
