Answer:
Replacement rate
Explanation:
In biology, replacement level or replacement rate refers to the amount number of offspring required to be produced to keep the level of population at a stable state without causing it to much decease.
Scientists use the replacement rate of plant and animal specie to assess the rate at which the population is reproducing at a stable level or are at some threshold zone and need to be taken care of.
Here in question, we see that some specific properties of mustard plants are focused that, plant survives only one month during which it produces 50 flowers. each flower produces a fruit containing 20 seeds.
It clearly do not depicts the population size of mustard plant, or niche or fitness, it just describe the replacement rate that how many offspring does mustard plant produce to keep its population at a stable or steady state without being getting into a danger of extinction.
Hope it help!
Answer:
The correct match is given below:
Explanation:
- A flower containing a pistil, stamen, calyx, and corolla – Complete flower. When a flower consists of essential whorls pistil and stamen and accessory whorls calyx and corolla, the flower is said to be complete.
- The collective term for the petals of a flower- Corolla. The corolla is a accessory whorl which consist s of its unit called petal.
- It has pistils, but no stamens - Female flower. A flower with only pistil is called unisexual pistillate flower.
- A stalk which supports the anther – Filament. A typical stamen consists of an anther, connective and a filament.
- A flower that lacks one or more of the following parts: pistil, stamen, calyx, or corolla corolla.—Incomplete flower. A flower which lacks any of the essential or accessory whorl is called incomplete flower.
- A flower that has male parts only – Male flower. A flower with only stamen is called unisexual staminate flower.
- A spore produced by meiosis – Meiospores. Spores can produced by mitosis or meiosis. If it is produced as a result of mitosis it is said to be mitospores.
The answer to this one is true
The cell membrane consists of three classes of amphipathic lipids: phospholipids, glycolipids, and sterols. The amount of each depends upon the type of cell, but in the majority of cases phospholipids are the most abundant, often contributing for over 50% of all lipids in plasma membranes.
Answer: Provides support for the blade of the leaves.
Explanation:
Vascular tissues are conducting tissues formed from specialized cells . The two conducting vascular tissues in plants are xylem and phloem.
Xylem tissue transport water and nutrients from plant roots to all part of the plants. Phloem transport sugars. It also provide structural support for plants. Vascular tissues run through the veins of the leaves and provide support. Vascular tissues are found in vascular plants.
