PLANT REPRODUCTION (Science Year 5, Unit 2)

Last day we were talking about PLANT NUTRITION. We are going to review today using one of our THINKING ROUTINES: QUICK WRITE / QUICK DRAW.  Remember to draw and write as faster as you can with the ideas you had about last day lesson.

Today we are going to learn a bit more about how do plants reproduce. This STOPMOTION video will help you to understand.

• At the end of the video you have to  answer these following questions. 
• What is it needed for POLLINATION?
• Do you think that just the bees can help with transportation?

SEXUAL REPRODUCTION

• Flowers are the reproductive organs of the plant.
• The stamen are the male. They produce polen.
• The ovary is the female part. It produces ovules which  becomes seeds.

POLLINATION

• Tiny pollen grains form on the stamens.
• POLLINATION is teh movement of pollen from stamens to ovary. 
• It used to take place in the same plant.
• Wind and insects also carry plant to other plants. 

SEEDS AND FRUITS

• After pollination the flower changes.
• Petals fall and ovary grows. It becomes a fruit with seeds.
• The fruit is ripe, it falls to the ground and the seeds fall out. 
• The seeds germinate: they open, and small roots and tiny leaves grow.

ASEXUAL REPRODUCTION

• Some plants reproduce without flowers or seeds:
• TUBERS: they are underground stems. It develops roots and a stem rise above the ground.  For example he potato.
• BULBS: they also grow underground. For example onions
• STOLONS: These are stems which extend acroos the ground. Roots grop an a new plant begins. For example strawberries. 

LET'S PRACTISE ALL WHAT YOU HAVE LEARN DURING THIS TOPIC WITH THE FOLLOWING ACTIVITIES. 

PLANT NUTRITION (Science Year5, Unit 2)

Try to review what we have learnt about plants the last lesson. We are goint to use a THINKING ROUTINE: THINK-PAIR-SHARE. Think: three ideas about the last lesson, PAIR: talk about these three ideas to your partner, SHARE: we will talk with all the class so we can create a small mind map about it.

LET'S HAVE A LOOK TO THIS VIDEO TO START WITH THE TOPIC:

• At the end of the video you have to create a picture in your notebook in which you represent the process of PHOTOSYNTHESIS.

RESPIRATION:

• Plants breathe.
• They take oxygen and release carbon dioxide. 
• It takes place in leave continually, day and night. 

PLANT NUTRITION:

• Plants are autotrophs: they make their own food.
• They need sunlight, carbon dioxide, water and mineral from the soil.

WATER AND MINERALS

• They are importann for plant nutrition.
• In the soil minerals are dissolved in water.
• Plants absorved water through the roots.
• RAW SAP: The nutrients travel up from the stem to the leaves.

PHOTOSYNTHESIS

• It enables plant to make food using sunligth, carbon dioxide, water and minerals.
• It takes place in the lives.
• In the leaves raw sap mix with carbon dioxide and becomes ELABORATED SAP.
• ELABORATED SAP is the food for the plant.
• Sunlight is very important for the photosynthesis so it only takes place during the day.
• During this process the plants release oxygen.

LET'S PRACTICE ALL WHAT YOU HAVE LEARN PLAYING THIS GAME

PLANTS (Unit 2, Year 5)

Today we will start with a new topic during our Science Lessons. During a couple of weeks we will talk about PLANTS. First of all it would be good to start with a THINKING ROUTINE: THE TRAFFIC LIGHTS, we will use this to check what you remember or know about plants.

We can watch a video to introduce the topic. Please during the video we will deal with a new THINKING ROUTINE: HOT WORDS, write down in your notebook important words (just words) about the video. 

PLANT GROUPS

Plants have roots, stem and leaves.

• ROOTS: they are in the soil. They absorbed from the soil through the roots. 
• STEM: it supports the leaves. It transports water and nutrients to the leaves.
• LEAVES: They are used to breathe and make plant's food. 

FLOWERING PLANTS

It is the biggest group of plants. 

• GYMNOSPERMS: 
  
• Small flowers, but no fruit.
• Seed are together in a small cone.
• Most of them are tree: Pine trees.
• ANGIOSPERMS:
• They have flowers
• They have fruit.
• Chessnut trees.

NON-FLOWERING PLANTS

It is the smallest group of plants. They need shade and moisture.

• MOSSES: 
• Small plants.
• They live on rocks, trees and ground.
• FERNS:
• They are larger mosses.
• They have thick, underground stems and big leaves.

LET'S PRACTISE WITH THIS CROSSWORD
