Modes of Reproduction in Plants

Modes of Reproduction in Plants

Week 6

Like other organisms, plants can also reproduce using different ways. In the previous lesson, you learned about how plants undergo sexual reproduction.

At this point, you will recognize other means of plant reproduction, specifically, through vegetative propagation. Vegetative propagation is an asexual reproduction in plants using different parts like stem, roots, and leaves to produce new plants. Asexual reproduction does not involve the use of seeds to propagate. 

Multiple Choice

The flower´s female sexual organ is :

• The pistil

• The stamens

• The stigma

• The ovule

Multiple Choice

What is inside the fruit?

• There are flowers.

• There are pistils.

• There are seeds.

Multiple Choice

What is the calyx?

• It is the reproductive system of the flower.

• It is a ring around the flower

• It is the stem of the flower

Multiple Choice

A flower has got...

• It has got stamen, pistil, petals, sepals, fruit and seeds.

• It has got a long stem and one petal.

• It has got fruit and seeds.

Multiple Choice

Which is the male organ of a flower

• Carpel

• Stamen

• Ovule

• pollen

Multiple Choice

Horse Radish (Malunggay)

• flowering

• non-flowering

Multiple Choice

Mosses (Lumot)

• flowering

• non-flowering

The previous lesson provides you the understanding about flowers as reproductive organ of fruit-bearing plants to produce seeds to grow new plants. In general, plants are classified into two major groups, flowering and non-flowering plants. 

Flowering plants are those that have an obvious flower as accessory organ. In botany (branch of science that deals with the study of plants), they are called as ‘angiosperms’.

Plants that belong to angiosperm family reproduce by sexually by means of their flowers. The presence of flowers may give clue that the plant produce seeds that mature within the fruits. 

There are two groups of angiosperms, dicotyledonous and monocotyledonous plants. Dicotyledonous plants are plants with netted veins and with two cotyledons in its embryo. Some examples of dicotyledonous plants are beans, peas, daisies while monocotyledonous plants are bamboos, bananas and lilies. 

Learning Task 1:

Observe your surrounding. List down the plants that possess the given description on the next slide of monocot and dicot.

Open Ended

List down the plants that possess the given description of monocot.

Open Ended

List down the plants that possess the given description of dicot.

Flowers are important for plants to bear fruits and produce seeds. However, there are also plants that do not use flowers for reproduction. These plants are called non-flowering plants. 

Learning Task 2:

There are nonflowering plants that do not produce flowers and seeds. There are plants that produce spores . There are plants where seeds are not developed inside the parts of the flowers .

In this activity, try to re arranged the jumbled letters to know these plants. 

Learning Task 3:

Based on the given description, identify the classification of the plants.

Multiple Choice

They are small plants that produce spores for reproduction instead of seeds and don't grow flowers, wood or true roots.

• gymnosperm

• spores

Multiple Choice

Ferns generally reproduce by producing spores. Similar to flowering plants, ferns have roots, stems and leaves.

• gymnosperm

• spores

Multiple Choice

They produce cone-bearing seeds. All living conifers are woody plants, and most are trees. Pines are typical examples of conifers.

• gymnosperm

• spores

Learning Task 5:

Create herbarium scrapbook.

A herbarium is an album or scrapbook of compressed flowering non flowering plants. It may contain all parts or some parts of plants.

To make a herbarium, follow the following steps :

• 1. Collect plants or plant parts. Compress using an old book or any material where you can platten the parts.

• 2. Paste or glue them on each page.

• 3. Indicate the name of the plants and its classification.
