Natuurwetenschappen: KT1: All you need is flowers p1-p12

what are the main parts of a plant (indicate on an image)

- flowers

- stems

- leafs

- roots

what are the main parts of a plant root (indicate on an image)

- primary (tap)root

- lateral root

- root hairs

what is a primary (tap)root

a thick root that grows directly downwards

what is a lateral root

roots branching of the primary root

what are root hairs

fuzzy outgrowth on the tip of a root

what is the function of a plant root

absorption of water and minerals and to secure the plant in the soil

roots can differ in:

- growing site (overgrown or ondergrown

- build (primary taproot with lateral roots or fibrious roots

draw a taproot and a fibrous root

dddd

what are the main parts of the stem

- the node (the uneven part where the leaf is attached tot the stem)

- the internode (the even part between the knots)

draw an image of it

dddd

what is the function of the stem

to absorb sunlight/ reach sunlight, channels water to the leaves, carries leaves, buds, flowers or fruits

roots can differ in

- growing site (overgrown or undergrown)

- growth direction (vertically or horizontally)

what are the main parts of the leaves and draw this in an image

- petiole (or leaf stalk)

- leaf apex

- midrib

- secondary vein

- venules

- margin

- leaf blade

- mesophyll

what is petiole or leaf stalk

the stalk that connects the leaf with the stem

what is leaf apex

tip of the leaf blade

what is the midrib

the main vein in the centre of the leaf blade and connected to the petiole

what is the secondary vein

the veins branching from the midrib

what are venules

veins branching from the secondary veins

what is margin

the boundary edge of the leaf

what is the leaf blade

the flat and green part of the leaf with veins and venules

what is the mesophyll

tissue between the venules

what are the two major parts of the leave

the leaf blade and the petiole (leaf stalk)

what do plants contain

starch and glucose

explain how lugol show the presence of glucose/starch (which colour changes happen and what this means)

apple: stayed orange

potato: turned black

bean: turned black

leaf: turned black

explain how diastix show the presence of glucose/starch (which colour changes happen and what this means)

apple: turned brown

potato: turned green and a bit brown

bean: stayed blue

leaf: stayed blue maybe a bit green

what is the conclusion of that

plants contain starch and glucose

what is starch

a chain of glucose molecule

what do plants get from the soil through their roots

water and dissolved substances or minerals

how do the absorbed substances travel

from the roots through the stem to the leaves
