True/False
Answer the question
???????
100
In plants, the majority of photosynthesis occurs in the stem tissues.
False
Photosynthesis mainly occurs in the plant's leaves. The stem serves mainly as a support structure and a conduit for transporting water and nutrients.

What is the role of nectar in flowers?
Nectar in flowers serves as a sugary reward for pollinators like bees and butterflies. When pollinators visit flowers to collect nectar, they inadvertently transfer pollen, aiding in plant reproduction. This mutualistic relationship benefits both parties.

soil free
Orchids don't need soil to grow: they get all the nutrients they need from air.

What is the process called when an insect takes pollen from one flower and takes it to another?
Cross-pollination.
200
1 meter per day
Bamboo is the fastest growing plant on earth. Some species of bamboo can grow more than 1 meter per day, which is about 4 cm per hour. No other plant grows faster.
300
there are few black flowers in the world
False
there are NO black flowers in the world

What is the longest blooming flower?
Anthurium has the longest blooming flowers. This tropical plant produces pretty white, pink, maroon or orange flowers that can bloom up to 8 weeks.
300
Steel
By the ability to withstand wind without deformation, the mechanical fabric of higher plants is stronger than steel.
400
Nitrate-fixing bacteria in the soil take nitrate gas and turn it into a usable form for plants.
FALSE
Nitrogen-fixing bacteria in the soil take nitrogen gas and turn it into a usable form for plants.

How do deciduous trees prepare for the winter season?
Deciduous trees prepare for winter by shedding their leaves, a process called abscission. This reduces water loss and minimizes the risk of damage from freezing temperatures. Shedding leaves also allows the tree to conserve energy during the dormant period.

corpse
The largest flower in the world can be up to ten feet tall and three feet wide, and it can weigh up to 24 pounds! It is called the Titan Arum (Аморфофаллус титанический ) and it has a distinctive smell of rotting flesh, hence why it is also known as the "corpse flower".

Artichokes and broccoli are flowers.
true

How do plants adapt to water-stressed environments, and what are some structural and physiological adaptations they employ for water conservation?
In water-stressed environments, plants have evolved various adaptations to conserve water. These include features like reduced leaves (sclerophyllous leaves), thick cuticles, and sunken stomata to minimize water loss through transpiration. Some plants, such as succulents, store water in specialized tissues, while others, like the deep-rooted xerophytes, access water from deeper soil layers.
