Name a plant that forms seeds but no fruits and another plant that forms fruits but no seeds. (2024)

Hint: A scientist divided the plant kingdom into two sub-kingdoms mainly based on the presence or absence of seeds in 1883. The sub-kingdom which can produce seeds are further divided based on whether they flower or not.

Complete answer:
Eichler in 1883 divided the plant kingdom into Cryptogams and Phanerogamae. Lower plants in which sex organs are hidden and seeds and flowers are absent were grouped under Cryptogamae. It includes thallophytes(algae), bryophytes, and pteridophytes. Phanerogamae is subkingdom for the higher plants in which sex organs are evident and seeds are present. It included gymnosperms and angiosperms. Phanerogamae is further divided into non-flowering plants i.e gymnosperms and flowering plants i.e angiosperms. Thus, Gymnosperms are the plants that form seeds but not fruits. E.g. Cycas, Pinus, Cedrus. Parthenocarpic plants are angiosperms that form fruits but no seeds. E.g. Banana, Pineapple.

Additional Information:
In ‘Gymnosperm’, an ovary wall does not enclose ovules and they remain exposed, both before and after fertilization. Remember, after fertilization, the ovules develop into seeds, the ovary develops into fruit, and the ovary wall into the fruit wall. But, in gymnosperms, after fertilization, the seeds developed from the ovule, are not covered i.e. are naked. Seeds are exposed to modified leaves known as sporophylls forming cones or strobili. Thus gymnosperms are fruitless plants.

Name a plant that forms seeds but no fruits and another plant that forms fruits but no seeds. (1)

Parthenocarpic plants undergo parthenocarpy which is defined as the formation of fruits without fertilization. One male gamete fuses with an egg cell while the other fuses with two polar nuclei. This process is called double fertilization which is unique to angiosperms. In parthenocarpic plants, however, the fruit develops from the ovary without double fertilization. Thus, parthenocarpic plants are also known as seedless plants. E.g: Banana, Fig, and Pineapple

Note: Reasons for parthenocarpy includes :
-Pollination failure, or nonfunctional eggs or pollen grains.
-Chromosomal imbalance such as in Banana which has a triploid set of chromosomes as opposed to a diploid set of chromosomes.

FAQs

What is a plant with seeds but no fruit? ›

Thus, Gymnosperms are the plants that form seeds but not fruits. E.g. Cycas, Pinus, Cedrus.

What fruit is formed without seeds? ›

Parthenocarpic Fruits. Many species and cultivars produce fruit that either lack seeds or have no viable seeds. The production of such seedless fruits is known as parthenocarpy and is common for the horticultural varieties of banana, pineapple, cucumber, tomatoes, figs, oranges, grapes, kiwi, blackberry, pepper, etc.

Which of the following types of plants will produce a seed but no fruit? ›

There are many plants that produce seeds but not fruit. Examples include ferns, mosses, and some types of algae. These plants reproduce by producing spores or seeds, but they do not produce a fleshy or edible fruit like many flowering plants do.

What is the name of the plant that does not produce seeds? ›

Plants such as ferns and mosses are called nonflowering plants and produce spores instead of seeds. There is also another group called the Fungi, that include mushrooms, and these also reproduce by spores.

Is any plant with seeds a fruit? ›

What is a plant with seeds but no flowers? ›

Answer and Explanation:

Plants that produce seeds but no flowers, like pine trees, are called gymnosperms. This contrasts with angiosperms which do produce flowers around their seeds. Another way to phrase this is that gymnosperms bear "naked" seeds, while angiosperms do not.

Is a cucumber a fruit? ›

Because cucumbers have seeds in the middle and grow from the flower of a cucumber plant, they are botanically a fruit. Botanical vegetables may be other edible structures of a plant, such as the leaves, stems and roots, and they do not have seeds.

Is a pumpkin a fruit? ›

Answer. A pumpkin, from a botanist's perspective, is a fruit because it's a product of the seed-bearing structure of flowering plants. Vegetables, on the other hand, are the edible portion of plants such as leaves, stems, roots, bullbs, flowers, and tubers.

What is the only fruit with seeds? ›

Strawberries are the only fruit that wear their seeds on the outside. The average berry is adorned with some 200 of them.

Which of the following plants can not produce fruit? ›

Cycas plants do not produce fruit, but they do produce seeds. Cycas belong to the division of gymnosperm containing the most primitive and simple seed plants. As a result, the seeds produced by these plants are not enclosed by fruits and are thus naked.

What are the three plants that reproduce without seeds? ›

Modern-day seedless vascular plants include club mosses, horsetails, ferns, and whisk ferns.
  • Club Mosses. The club mosses, or Lycophyta, are the earliest group of seedless vascular plants. ...
  • Horsetails. Ferns and whisk ferns belong to the division Pterophyta. ...

What are some examples of plants that reproduce without seeds? ›

10 Plants That Grow Without Seeds
  • Potatoes: Grown from tubers or “seed potatoes.”
  • Sweet Potatoes: Propagate from cuttings or “slips.”

  • Garlic: Grows from individual cloves.
  • Strawberries: Reproduce via runners or daughter plants.
  • Mint: Propagates easily from stem cuttings.

What two plants do not produce seeds? ›

Plants such as ferns and mosses are called nonflowering plants and produce spores instead of seeds. There is also another group called the Fungi, that include mushrooms, and these also reproduce by spores.

What are two plants that Cannot produce seeds? ›

Ferns and moss are both examples of primitive plants. They are flowerless or seedless plants.

Is there a plant without seeds? ›

False fruit is a fruit in which some of the flesh is not derived from the ovary but some adjacent tissues exterior to the carpel. False fruit is also called pseudo fruit or pseudo carp. Examples of such fruits are strawberry, pineapple, mulberry,apples, pears etc.

What are the 10 examples of non-flowering plants? ›

These non-flowering plants have been around for millions of years and are some of the most ancient plants on Earth. Non-flowering plants mostly fall into one of these groups: ferns, liverworts, mosses, hornworts, whisk ferns, club mosses, horsetails, conifers, cycads, and ginkgo.
