Why does my plant look sad?
Sometimes, it can be tricky to tell whether a plant is looking sad because it’s been underwatered, or because it’s gotten too much water and developed root rot.

What does a seed need to grow into a plant?
All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also. Some germinate better in full light while others require darkness to germinate. When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat.
How does the stem help the plant stay upright?
A plant’s roots sit below the soil and the stem grows above it. … They also anchor the plant to the ground and keep it steady. The stem carries water and nutrients to different parts of the plant. It also provides support and keeps the plant standing upright.
Which plant has separate sepals?
Answer: Flowers with joined sepals — Hibiscus, datura, cotton, tomato (anyone). Flowers with separate sepals — mustard, lotus, lily, jasmine, rose (anyone).
What are joined sepals?
Sepals: Sepal is the green-coloured part beneath the petals to protect rising buds. Some flowers have fused petals-sepals while a few have separated petals-sepals. Flower with joined sepals is Periwinkle (Sadabahar) Datura, Cotton and Hibiscus (China rose). Flower with separated sepals is Rose, Lotus and Magnolia.
Why do plants stand up at night?
Nyctinasty is the circadian rhythmic nastic movement of higher plants in response to the onset of darkness, or a plant “sleeping”. … Nyctinastic movements are associated with diurnal light and temperature changes and controlled by the circadian clock and the light receptor phytochrome. This is the plant sleeping.
How does water keep a plant rigid and upright?
When water escapes through the leaves into the air through transpiration, it provides a pulling force. This pulling force pulls water up and out a plant through tiny little tubes called the xylem. … Plants do not have bones to keep them upright – they rely on this turgidity to keep them upright and strong.
Are all the petals joined together or separate?
Above the sepals are the petals. Although flattened like the sepal, each petal is usually soft and coloured. Usually, the number of petals in a flower will be the same as the number of sepals. If the sepals of a flower are joined together, then its petals are separate and not joined.
What is the male part of the flower?
StamenStamen, the male reproductive part of a flower. In all but a few extant angiosperms, the stamen consists of a long slender stalk, the filament, with a two-lobed anther at the tip. The anther consists of four saclike structures (microsporangia) that produce pollen for pollination.
Who hold the plant upright?
StemsAnswer: Stems hold the plant upright and support it. They also transport water, minerals and sugars to the leaves and roots.
Do roots hold the plant upright?
Answer: Root absorbs water and minerals from the soil. Leaves hold the plants upright. Answer: Stem holds the plants upright. Roots conduct water to the leaves.
What plant part supports the stem?
Figure 30.2A. 1: Parts of a stem: Leaves are attached to the plant stem at areas called nodes. An internode is the stem region between two nodes. The petiole is the stalk connecting the leaf to the stem.
Can you find a plant in your house or in your neighborhood which has a long but weak stem?
Answer. Yes, there is a plant in our house which has a long but a weak stem. Its name is money plant. It is a climber.
What would happen if we break the stem of a plant?
The stem of a tender plant can be easily damaged by high winds, heavy rains or poor handling. This vital part of the plant transports the nutrients from the water and soil to its blossoms and leaves. If the stem becomes broken or bent, it can interrupt this flow and can cause your plant to die.
Do plants droop at night?
It is caused by phototropism. During the day, when light shines, the plant will grow towards the light. … This causes the effect that parts of the plant in shade grow harder than parts in light, and hence they bend towards the light. During night this effect stops and therefore the leaves will droop.
What absorbs water and minerals from the soil?
Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
