Question

A spore producing plant is
A. Rose
B. Bread mould
C. Potato
D. Ginger

Answer 1

Hint: A spore is a part of asexual or sexual reproduction which may be adapted for both survival and dispersal. Spores are also formed during unfavourable conditions so that the organisms can live for extended periods of time.

Complete Answer:
Fungi, Mosses and Ferns do not produce seeds or flowers. They propagate with spores that appear on the bottom of the fronds.

Let us analyse the given option to find out the correct answer.
Option A: Roses reproduce through either sexually - seedling and pollination - or asexually, such as when their stems root as they track along the terrain in fertile clay or when their roots give up new shoots from radical. Therefore, this is an incorrect answer.

Option B: Bread mould or Rhizopus is a similar sort of fungus. During asexual propagation, inside the sporangium the mould produces spores, and the spores reproduce inside it. When the sporangium cracks, open and all spores inside will drift out. The spores land on a point where they can transform into a new form, and start to grow. Therefore, this is the correct answer.

Option C: Potatoes are largely produced by vegetative processes (cloning). Potato tubers have eyes or nodes from which the new life starts. The new stems arising from each eye or nodes are known as sprouts which give life to the new plant. Vegetative seed can be either a complete tuber or a slice tuber. Therefore, this is an incorrect answer.

Option D: In ginger, vegetative reproduction happens through the rhizome. Rhizomes are stems which develop horizontally under the earth. In ginger, the underground stems are grown with food resources. The terminal bud develops upward to germinate the flowering shoot and the lateral buds grow out to produce new plants. Therefore, this is an incorrect answer.

Thus, option B is the correct answer.

Note: In vegetative reproduction, Spores are the generative cell formations of Fungi, Mosses and Ferns. Fern spores grow within tiny green caps on the bottom of the fronds, named sporangia. When the dusty spores are planted on a wet soil mix they provide small, heart-shaped forms known as prothallia. Each prothallus includes both female and male organs, enabling them to propagate and thus produce small new ferns.
