Answer and Explanation: The purpose of the enclosed seed in fruits is to attract the animals for seed dispersal.
What does enclosed seed mean?
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. Gymnosperm seeds are often configured as cones.
Which seeds are enclosed inside the fruit?
Angiosperms plants have enclosed seeds in the fruits. So, option A is the correct answer.
Why in angiosperms seeds are enclosed in fruits?
The seeds and fruits are the results of fertilization or sexual reproduction in plants. The ovary in angiosperms develops into the fruit whereas the ovules become the seeds enclosed within the fruit. Seeds are found both in gymnosperms and angiosperms. Example apple, cherry, and orange blossoms, before they bear fruit.
What is the main purpose of a seed?
Seeds are fertilised, mature ovules—the result of sexual reproduction in plants. Not all plants produce seeds, but those that do often rely on these seeds to replicate themselves over successive seasons and years.
What is enclosed by a fruit?
the seeds are enclosed by fruit.
Which fruit does not enclose its seeds?
Detailed Solution
A gymnosperm’s seeds are open to the environment. The word “gymnosperm” means “naked seed” and the seeds are not enclosed inside fruit, but are instead exposed or on the scales of cones, like a pine cone. SSC Stenographer Final Marks 2020 Declared.
Why the seeds of angiosperms are closed?
Seeds are surrounded by one or two integuments, which develop into a seed coat that is usually hard. They are enclosed in the ovary of a carpel and thus are protected from the elements and predators.
What are angiosperm seeds enclosed in?
ovary
Angiosperms (flowering plants) have seeds enclosed in an ovary. Flowers include ovaries and surrounding structures. Ripened ovaries make up a fruit.
What is difference between gymnosperms and angiosperms?
Angiosperms, are also known as flowering plants and having seeds enclosed within their fruit. Whereas gymnosperms have no flowers or fruits and have naked seeds on the surface of their leaves. Gymnosperm seeds are configured as the cones.
What is the relationship between fruit and seed?
The seeds and fruits are the results of fertilization or sexual reproduction in plants. The ovary in angiosperms develops into the fruit whereas the ovules become the seeds enclosed within the fruit.
What are seeds What do they contain and what is their function?
Seeds are the products of ripened ovule. Seeds contain two cotyledons or a single cotyledon as in cereals which help in providing food to the embryo (baby plane). These cotyledons are enclosed within the seed coat which also acts as a protective layer. On germination, seeds give rise to new baby plant.
What’s inside a seed?
Inside the seed there are is an embryo (the baby plant) and cotyledons. When the seed begins to grow, one part of the embryo becomes the plant while the other part becomes the root of the plant. Food for the plant is stored in the cotyledons. Some seeds when split apart seperate into two halves.
Are seeds alive?
Viable seeds are living entities. They must contain living, healthy embryonic tissue in order to germinate. All fully developed seeds contain an embryo and, in most plant species, a store of food reserves, wrapped in a seed coat.
Do all fruits have seeds?
Most fruits have seeds on their insides. However, the strawberry is the only fruit that has seeds on the outside. Some fruits have a shell on their outside, like a watermelon. The shell protects the juicy, sweet fruit inside.
What makes a fruit a fruit?
A fruit is a mature, ripened ovary, along with the contents of the ovary. The ovary is the ovule-bearing reproductive structure in the plant flower. The ovary serves to enclose and protect the ovules, from the youngest stages of flower development until the ovules become fertilized and turn into seeds.
How are fruits and seeds formed?
Seeds and fruits are formed by fertilization. In angiosperms, two structures are formed as a result of double fertilization – a diploid zygote and a triploid primary endosperm cell. The zygote develops into an embryo, whereas the endosperm cell gives rise to endosperm. It provides nourishment to the growing embryo.
Which plant has seed but no fruit?
Gymnosperms
Thus, Gymnosperms are the plants that form seeds but not fruits. E.g. Cycas, Pinus, Cedrus.
Who produce naked seeds?
gymnosperms
In gymnosperms (plants with “naked seeds”—such as conifers, cycads, and ginkgo), the ovules are not enclosed in an ovary but lie exposed on leaflike structures, the megasporophylls.
What is a group of seeds called?
Gymnosperms and angiosperms are the two major groups of seed plants.
What are closed seed plants?
Closed seeded plants: The angiosperms are vascular seed plants in which the ovule (egg) is fertilized and develops into a seed in an enclosed hollow ovary.
