Non-vascular plants have stems, roots, and leaves.

True
False

Correct Answer

A. False

Explanation

Non-vascular plants do not have true stems, roots, or leaves. These plants, such as mosses and liverworts, lack specialized tissues for conducting water and nutrients throughout their bodies. Instead, they rely on direct absorption from their surroundings. While non-vascular plants may have structures that function similarly to stems, roots, and leaves, they are not true counterparts to those found in vascular plants. Therefore, the statement that non-vascular plants have stems, roots, and leaves is false.

5.

Vascular plants have vessels that transport food and water to the xylem and phloem.

True
False

Correct Answer

A. True

Explanation

Vascular plants have specialized structures called vessels that are responsible for transporting food and water throughout the plant. These vessels include the xylem, which transports water and minerals from the roots to the rest of the plant, and the phloem, which transports sugars and other organic compounds from the leaves to other parts of the plant. Therefore, it is true that vascular plants have vessels that transport food and water to the xylem and phloem.

What is the benefit of hydroponics?

Doubles the crop yield
Makes the plants greener
Reduces the use of fertilizer
Enables crops to grow in areas with poor soil.

Correct Answer

A. Enables crops to grow in areas with poor soil.

Explanation

Hydroponics is a method of growing plants without soil, using a nutrient-rich water solution instead. This technique enables crops to be cultivated in areas with poor soil quality, where traditional agriculture may not be feasible. By providing the plants with all the necessary nutrients directly, hydroponics allows them to thrive even in environments where the soil is lacking in essential elements. This benefit of hydroponics opens up opportunities for agriculture in regions with limited access to fertile land, ultimately increasing food production and addressing food security challenges.

All angiosperms

Are seedless
Produce fruits
Have naked seeds
Are self pollinated

Correct Answer

A. Produce fruits

Explanation

Angiosperms are a group of plants that produce flowers and have enclosed seeds. One of the defining characteristics of angiosperms is their ability to produce fruits. Fruits are the mature ovaries of flowering plants and contain seeds. This adaptation allows angiosperms to protect and disperse their seeds effectively. Therefore, the statement "produce fruits" is a correct characteristic of all angiosperms.

8.

All gymnosperms

Have a limited growing season
Are pollinated by birds and bees
Are colorfull
Are green year around

Correct Answer

A. Are green year around

Explanation

Gymnosperms are green year-round because they are evergreen plants. Unlike deciduous plants that lose their leaves in the fall, gymnosperms retain their foliage throughout the year. This allows them to continue photosynthesizing and producing food even during the winter months. The green color is due to the presence of chlorophyll, which is essential for photosynthesis. Gymnosperms include conifers, cycads, ginkgoes, and gnetophytes, and they are known for their ability to thrive in various climates and environments.

Which part of a flower becomes a fruit?

Ovary
Petal
Sepal
Filament

Correct Answer

A. Ovary

Explanation

The ovary is the part of a flower that becomes a fruit. After fertilization, the ovary develops into a fruit, which contains the seeds of the plant. The ovary protects and nourishes the developing seeds, and as the fruit matures, it often becomes fleshy or develops a hard outer layer. This allows the seeds to be dispersed and increases the chances of successful reproduction for the plant.

Which factor helps you to tell the difference between a monocot and a dicot?

Number of seed leaves
Number of flower petals
Arrangement of vascular tissue
All of the above

Correct Answer

A. All of the above

Explanation

The factor that helps to distinguish between a monocot and a dicot is all of the above. The number of seed leaves, number of flower petals, and arrangement of vascular tissue are all characteristics that can be used to differentiate between these two types of plants. Monocots typically have one seed leaf, while dicots have two. Monocots often have flower parts in multiples of three, while dicots have flower parts in multiples of four or five. Additionally, the arrangement of vascular tissue differs between monocots and dicots.

List 3 ways that seeds are dispersed.

Correct Answer
animals, wind, water

Explanation
Seeds are dispersed through various means to ensure their survival and distribution. Animals play a crucial role in seed dispersal as they consume fruits or seeds and later excrete them in a different location. This process aids in the spread of seeds over a wider area. Wind dispersal occurs when lightweight seeds are carried away by air currents, allowing them to travel long distances. Water dispersal is another method where seeds are transported through bodies of water, such as rivers or oceans, enabling them to reach new habitats. Therefore, animals, wind, and water are three common ways in which seeds are dispersed.

The leaves of trees change color due to the loss of what pigment.

Water
Chlorophyll
Chromatin
Photosynthesis

Correct Answer

A. Chlorophyll

Explanation

The leaves of trees change color due to the loss of chlorophyll pigment. Chlorophyll is responsible for the green color in leaves and is essential for photosynthesis. As the days become shorter and temperatures drop in the fall, trees stop producing chlorophyll, causing it to break down and be reabsorbed by the tree. This reveals other pigments such as carotenoids and anthocyanins, which give leaves their vibrant fall colors.

What supports the weight of kelp?

The air
The ocean
The wind
The animals

Correct Answer

A. The ocean

Explanation

Kelp is a type of seaweed that grows underwater in the ocean. It is anchored to the ocean floor by a holdfast, which helps support its weight. The ocean provides the necessary buoyancy for the kelp to float and grow vertically towards the surface. The water also helps to distribute the weight of the kelp evenly, preventing it from sinking or being carried away by currents. Therefore, the ocean supports the weight of kelp.

Spikes on a cactus serve what purpose?

To let oxygen in
To let oxygen out
To suck in water
Defense

Correct Answer

A. Defense

Explanation

The spikes on a cactus serve the purpose of defense. Cacti are often found in arid environments where water is scarce, so their spikes act as a deterrent to prevent animals from approaching and potentially damaging the plant. The spikes can cause pain or injury to predators, making it less likely for them to attempt to eat or disturb the cactus. This defense mechanism helps the cactus to survive and thrive in its harsh habitat.

Rate this question:

16.

When do cacti open their flowers?

Day
Night
Both answers above
Never

Correct Answer

A. Night

Explanation

Cacti open their flowers at night. This is because cacti are adapted to arid environments, where daytime temperatures can be extremely high. Opening their flowers at night allows them to conserve water and reduce the risk of dehydration. Additionally, opening their flowers at night increases the chances of pollination, as nocturnal pollinators such as moths and bats are more active during this time. Therefore, the correct answer is "night".
