Hello boys and girls, how are you today? Welcome to a new Natural Science Unit, Unit number 4, Plants.
00:00:00
In this unit we are going to learn about different things related to plants.
00:00:08
Are plants born? Do plants grow, reproduce and die?
00:00:14
Do plants eat food? Can plants move around?
00:00:21
Do plants breathe?
00:00:26
We are starting with Unit 4, Lesson 1, Classification of plants.
00:00:33
First of all, what are plants?
00:00:40
Plants are living things.
00:00:43
The plant life cycle includes the following stages.
00:00:44
Plants are born, grow, reproduce and die.
00:00:49
born, grow, reproduce and die. Plants, as all living things, perform three vital
00:00:54
functions. Nutrition, reproduction and interaction. Do you remember the parts of
00:01:09
a plant? We learned this last year in second grade. Roots, stem, leaf and flower.
00:01:23
Remember roots, stem, leaves and flower. Plants have roots, stem, leaves and flower.
00:01:33
The roots absorb water and minerals from the ground. The stem transports this
00:01:46
water and minerals throughout the plant. The leaves make the food. They use water,
00:02:06
minerals, air and sunlight. The flower makes the seeds for plant reproduction.
00:02:24
Remember this only happens in flowering plants. Non-flowering plants do not
00:02:44
produce the seeds in the flower. Classification of plants. There are many
00:02:52
types of plants number one according to their stem plants with different stem
00:03:02
grasses bushes and trees remember grasses bushes and trees grasses have a
00:03:12
flexible green stem and they are short. Bushes have a thick stem but it's not a
00:03:33
trunk. They are shorter than trees. Trees have a thick stem called trunk and they
00:03:49
are taller than bushes and grasses. Number two, classification of plants, loose
00:04:09
or keep their leaves. Plants can be deciduous or evergreen. Remember evergreen
00:04:23
deciduous. As we can see here they are different depending on the season.
00:04:37
Evergreen, they are very similar all the year. Evergreen plants always have leaves
00:04:47
in spring, summer, autumn and winter. On the other hand, deciduous plants lose
00:05:04
their leaves in autumn. As we can see here, in spring new leaves start to grow
00:05:15
in summer the tree has plenty of leaves in autumn the leaves start to change
00:05:23
color and fall to the ground and in winter deciduous trees have no leaves
00:05:33
classification of plants three with seeds and without seeds seed plants seed
00:05:42
plants produce seeds. All the plants that you can see here in this PowerPoint
00:05:55
slide produce seeds. As you can see from the seed it starts to grow a new plant.
00:06:02
There are different types of seeds. Seed plants use seeds to reproduce. Seed
00:06:11
plants. There are two different types of seed plants. Gymnosperms, like an ice
00:06:28
cream cone. Angiosperm, flower. Gymnosperm, without flower they have cones. For
00:06:38
example pine trees produce seeds inside a cone. Angel sperms with flowers they
00:06:53
have fruits. For example, almond trees produce fruit with seeds inside. On the
00:07:06
other hand we have non-seed plants. Non-seed plants produce spores. Non-seed
00:07:20
plants use spores to reproduce. Non-seed plants. Ferns and Moses. Ferns have roots,
00:07:32
stems and leaves. Fern spores are on the underside of the leaf. Mosses have stems
00:07:52
and leaves but not true roots. Moss spores are inside capsules. Remember we
00:08:09
need plants and plants need us.
