Q

What is the first sign of a seed sprouting?

Study These Flashcards
A

The hypocotyl appears as the seed swells and bursts.

Hypocotyl = First Hope.

24
Q

Why are seeds light and feathery in some plants?

Study These Flashcards
A

To aid in wind dispersal.

Feathered Seeds Fly.

25
Why do some plants have thorns on their stems?
To protect against predators. ## Footnote Thorns = Tough Guards.
26
How do broad leaves like those of aloe benefit plants?
They store water for use in dry conditions. ## Footnote Broad Leaves = Water Banks.
27
Why are some fruits smooth and thin-skinned?
To be easily eaten and digested by animals, aiding seed dispersal. ## Footnote Thin Skin Travels.
28
Why do soft-stemmed plants grow better from cuttings?
They root more easily than plants with hard stems. ## Footnote Soft Stems, Easy Growth.
29
What are the key conditions for a cutting to grow roots?
Water, warmth, and sunlight. ## Footnote Water + Warmth = Roots.
30
How can you test if something is living or non-living?
Check if it performs the seven life processes: grow, reproduce, feed, move, breathe, excrete, sense. ## Footnote GRaF Me BE Sense.
31
Why do some living things appear non-living temporarily?
They may require specific conditions to show life, e.g., seeds needing water and warmth to grow. ## Footnote Life Needs Activation.
32
Why do plants have different types of roots?
To adapt to their environment, e.g., big trees have strong roots for anchoring, while smaller plants may have thinner roots. ## Footnote Roots Reflect Needs.
33
What are the functions of fruits in plants?
Fruits develop from flowers and contain seeds, aiding in plant reproduction. ## Footnote Fruits Form Future Plants.
34
How do thick stems benefit plants in arid regions?
They store water, helping the plant survive dry conditions. ## Footnote Thick Stems, Water Stores.
35
Why do some flowers have dull colors?
To avoid attracting animals, which is common in grasses. ## Footnote Dull Flowers, No Pollinators.
36
How do thorny stems protect plants?
They deter animals from eating the plant. ## Footnote Thorns = Tough Protection.
37
What conditions are necessary for germination?
Warmth, light, water, and air. ## Footnote WLWA for Growth.
38
What happens to a seed coat during germination?
It splits open to allow the seedling to emerge. ## Footnote Seed Coat Splits, Life Begins.
39
Why is oxygen important for germination?
It supports the energy required for the seed to grow. ## Footnote Oxygen = Germination Fuel.
40
What parts of a seedling emerge first?
The root (radicle) and then the shoot. ## Footnote Root First, Shoot Follows.
41
What happens if a plant gets too much or too little warmth?
It struggles to grow or becomes stunted. ## Footnote Warmth Balance = Growth.
42
Why do plants need strong stems?
To support leaves and flowers for photosynthesis and reproduction. ## Footnote Strong Stem, Strong Plant.
43
How do thin-skinned fruits aid in seed dispersal?
Animals eat the fruits, digest the flesh, and disperse the seeds. ## Footnote Thin Skin Travels Far.
44
How do broad leaves help plants in wet climates?
They collect more sunlight for photosynthesis. ## Footnote Broad Leaves, More Light.
45
What is an example of a non-living thing that used to be alive?
Wood that has burned in a fire. ## Footnote Burned Wood = Once Alive.
46
Why do living things need to excrete waste?
To remove harmful substances and maintain balance. ## Footnote Excretion = Clean Living.
47
How do stems contribute to photosynthesis indirectly?
They support leaves, allowing them to access sunlight. ## Footnote Stems Lift Leaves to Light.
48
Why are seeds important for plants?
They enable reproduction and growth of new plants. ## Footnote Seeds = Next Generation.
49
How do plants with thorns survive better in their environment?
Thorns deter herbivores from eating them. ## Footnote Thorns = Armor.
50
Why do some plants have thick, waxy leaves?
To reduce water loss and store moisture. ## Footnote Waxy Leaves Save Water.
51
What happens if a plant does not get enough air?
It cannot make food through photosynthesis and will die. ## Footnote No Air, No Food.
52
Why is warmth crucial for seed germination?
It activates enzymes needed for growth. ## Footnote Warmth Wakes Seeds.
53
How do bright flowers increase a plant’s chances of reproducing?
They attract pollinators like bees, which transfer pollen. ## Footnote Bright Colors Bring Bees.
54
What is pollination?
The transfer of pollen from one flower to another to allow fertilization. ## Footnote Pollination = Pollen Sharing.
55
Why do some fruits have hooks or spines?
To stick to animals and disperse seeds. ## Footnote Hooks Hitch a Ride.
56
What are the benefits of wind dispersal for seeds?
It allows seeds to spread over a wide area for growth. ## Footnote Wind Wings for Seeds.
