Okay so I was doing my homework and couldn't find the answer to this on the work sheet but i found the mandible is for the tissue part and for the nectar part i have not found out yet.
insects use mandibles to chew plant tissues and others use siphons to lap up nectar.
The mandible is used for chewing plant material, and the proboscis is used for sucking nectar; i.e. the straw-like mouth of a butterfly.
Honey bees chewing plant tissue and lapping up nectar do pollination also.

Daddy-long-legs, or Harvestmen, eat live insects, mostly aphids. Some species feed on dead insects or plant juices.
Mosquitos (but only pregnant females), horseflies, fleas, lice, and some true bugs (Hemiptera) though none of those feed on humans.
A peacock (peafowl), like many other birds, is a first and second order consumer. It is an omnivore and eats plant matter, insects, and small arthropods. (Some insects eat other insects, so in that case the peacock might be said to be a tertiary consumer.)
Insects can help the environement A LOT!Many of the insects are thought to be pests by humans. But there are hundreds of insects that help the human race in various ways. Insects are necessary to pollinate flowering plants, without the active help of insects thousands of plant varieties would have become extinct. Insects produce substances such as wax, honey and silk which are then used by humans in a large number of applications and for direct consumption. Some insects act as scavengers, thus helping to maintain the ecological balance on the earth.The ecosystem heavily relies on insects for decomposition, nutrient and energy recycling, soil aeration, and pollination. Insects are helpful as saprophytes collecting and recycling garbage wastes. Dead organisms are broken down by insects and this assists in the formation of new life.
Insects that live on their own - as opposed to social insects.

Chewing of plant matter is the commonest method, but some insects such as the much loved Lady Beetles, get by by sucking the juices from a plant. The larval stage of others, attach themselves to the root of a plant, only to emerge when they are ready to emerge from the chrysalis - such as Cicadias.
Disfigure, harm or kill is what a pest can do to a plant. Burrowing into the tissue leaves unsightly markings on a leaf surface while defoliating and feeding upon sap runs counter to proper development and growth.
Some insects visit a plant to eat it. e.g. termites, carpenter ants.Some insects visit a plant to drink its juices or sap. e.g. male mosquitoes.Some insects visit the flowers of a plant to collect its sugary nectar. e.g. honey bees.etc.
yes the venisflytrap and the pitcher plant can
The mouthparts of sucking insects are developed for piercing and sucking. These pests damage plants by inserting their mouthparts into plant tissue and removing juices. Heavily infested plants become yellow, wilted, deformed or stunted, and may eventually die. Some sucking insects inject toxic materials into the plant while feeding, and some transmit disease organisms. Source: http://umaine.edu/ipm/ipddl/publications/5039e/

Plant tissue culture usually takes some time to grow. Depending on the culture taken, it can take a couple weeks.
One cost to the plant of insect pollination is the energy required to produce nectar and pollen, which serves as a reward to attract insects. Additionally, there is a risk of damage to the plant's reproductive structures by the visiting insects. Finally, some insect pollinators may also inadvertently transfer pollen from other plant species, leading to potential hybridization and reduced genetic purity.
some will die some will split and grow, depents of the plant and amount of tissue damage.
Different insects eat different things. It varies a lot. Some food items are flower nectar, plant leaves, plant remains, smaller insects and even dead human skin (the preferred food of the dust mite).
