Hi everyone, so in the last two videos we practiced the classification of plants 00:00:05
and then in the second video we practiced the plants reproduction and 00:00:12
then in this video we're going to practice how do plants or do plants need 00:00:17
food and we're going to see also how water, sunlight, carbon dioxide, 00:00:25
and oxygen help plants in making food their food so let's start with the idea 00:00:35
of photosynthesis plants need energy they make their energy through the 00:00:46
synthesis mirrored photo synthesis plants need energy they make their 00:01:02
energy through the photo synthesis so let's do that math how do photosynthesis 00:01:21
take place. So photosynthesis equals minerals plus water plus sunlight plus 00:01:38
carbon dioxide equals energy and oxygen so minerals plus water plus sunlight 00:01:57
plus carbon dioxide it calls energy which are the fruits and oxygen 00:02:19
Mirror word photosynthesis equals minerals plus water plus sunlight plus 00:02:31
carbon dioxide equals energy plus oxygen 00:02:55
so photosynthesis equals minerals plus water plus sunlight plus carbon dioxide 00:03:13
equals energy plus or N, oxygen. So why are plants important for us humans? Plants 00:03:27
need carbon dioxide and release oxygen. For us humans, humans need oxygen and 00:03:45
release carbon dioxide. So plants release oxygen and need carbon dioxide. For 00:04:03
humans we need oxygen and release carbon dioxide. Mirror word. Why are plants 00:04:17
important for humans. Plants need carbon dioxide and release oxygen. Humans need 00:04:31
oxygen and release carbon dioxide so in your notebook I think you wrote this one 00:04:52
photosynthesis and you also draw this one and we're going to practice this 00:05:08
later so number one is water and then minerals the number three carbon 00:05:14
dioxide number four sunlight number five stem and leaves and number six oxygen 00:05:22
okay we're going to talk about them in the next slides 00:05:34
Number one, the roots absorb water from the soil. Number two, the roots absorb 00:05:38
minerals from the soil number three the leaves absorb carbon dioxide from the 00:05:56
air number four the leaves absorb sunlight number five water and minerals 00:06:11
pass through the stem and leaves stem to the leaves and number six plants make 00:06:27
energy and release oxygen mirror word the roots absorb water from the soil 00:06:41
Number two, the roots absorb minerals from the soil. The leaves absorb carbon 00:07:01
dioxide from the air. Number four, the leaves absorb sunlight. Number five, water 00:07:18
and minerals pass through the stem to the leaves and number six plants make energy and release 00:07:35
oxygen respiration plants need oxygen to breathe so this happens during daytime and nighttime but 00:07:56
let's see the difference. Mirror word. Plants need oxygen to breathe. This 00:08:23
happens during daytime and nighttime. Mirror word. Respiration. Plants need 00:08:40
oxygen to breathe this happens during daytime and nighttime so let's see the 00:08:53
difference during daytime photosynthesis plants produce oxygen they release the oxygen that they 00:09:10
do not need during nighttime there is no Sun plants do not produce oxygen they 00:09:37
take it from the air. Mirror word. Daytime. Photosynthesis. Plants produce oxygen. They 00:09:59
release the oxygen that they do not need. Nighttime there is no Sun. Plants do not 00:10:25
produce oxygen they take it from the air so remember we need plants and plants 00:10:48
need us thank you for practicing with me bye-bye see you 00:11:07
